Pests

Numerous pests affect commercial vegetable production in New York. All stages of plant growth may be susceptible to insects or disease causing pathogens which may result in poor seedling emergence, reduced yields and quality issues. Similarly, weeds compete with vegetable crops for light, nutrients and water often reducing yields. Weeds can also act as a reservoir for insects and diseases. Furthermore, weed seeds and other parts can be a contaminant of certain vegetable crops.

Eastern New York Commercial Horticulture Program Specialists conduct research and educational programs on many important insects, diseases and weeds in New York. While not an exhaustive list, current information on many important vegetable pests can be found below. The most recent pest content is listed below but you can find more pests under the pest categories of Diseases, Insects, and Weeds.

Tar Spot in Sweet Corn: Be Alert!!

Ethan Grundberg, Vegetable Specialist
Eastern New York Commercial Horticulture

Last Modified: August 28, 2024

There is a new disease on the block for sweet corn in New York! Tar spot is a fungal disease found first in Indiana and northern Illinois field corn in 2015. It has since spread throughout the Midwest. The disease was found in western NY corn fields every year for the past 3 years, and in central NY last year. Tar spot has potential to severely reduce yields of susceptible corn varieties, so we are closely monitoring disease spread and impact.

New York State Department of Environmental Conservation (DEC) Commissioner Basil Seggos announced actions to limit the unrestricted use of pesticides that can harm bee and other pollinator populations. DEC is reclassifying certain products containing the neonicotinoid (neonic) insecticides imidacloprid, thiamethoxam, and acetamiprid as "restricted use" to ensure applications are limited to trained pesticide applicators in specific situations.  Restricting the use of these pesticides enables DEC to collect new data to determine where, when, and how they are used, as well as their potential impacts.

 


Testing the Feasibility of Using Red Sticky Card Traps to Monitor Spotted-Wing D

Laura McDermott, Team Leader, Small Fruit and Vegetable Specialist
Eastern New York Commercial Horticulture

Last Modified: March 3, 2022

Spotted-wing drosophila (SWD, Drosophila suzukii) continues to drive berry and cherry growers' spray schedules. Monitoring helps to determine when populations begin to build up, and therefore can help save growers spray applications in a late infestation year. This year we successfully tested red sticky card traps, baited with SWD lures, to detect first arrival of SWD in berry plantings and cherry orchards. The baited, red sticky traps provided good results for the SWD monitoring network. We found that the red sticky traps have potential for use by growers and consultants to monitor SWD pressure in at-risk fruit plantings. Grant funding was obtained, PI Laura McDermott, ENYCHP, to further test the red sticky traps and to educate growers and consultants on their use.

 


Weed Management Tips in Preparation of 2022 Herbicide Shortages

Laura McDermott, Team Leader, Small Fruit and Vegetable Specialist
Eastern New York Commercial Horticulture

Last Modified: March 3, 2022

Many growers in the US have been focused on predicted herbicide shortages in the upcoming field season. While the primary concerns have surrounded glyphosate and glufosinate, there is increasing apprehension that active ingredients of importance to vegetable growers may also be affected. Although the supply change is dynamic, chemical stocks may become, and remain, tight at the local or regional level as growers try to fill gaps in their toolboxes. 


Cold Temperature and Herbicide Storage

Chuck Bornt, Team Leader, Extension Vegetable Specialist
Eastern New York Commercial Horticulture

Last Modified: January 27, 2022

Cold temperatures can affect herbicide performance; applications of postemergence products under cool conditions may result in delays in symptom development and some treatments may fail altogether. Cold temperatures are also a concern for stored herbicides, particularly liquid products. Freezing (which may occur at temperatures below 32 F for some formulated products) can result in the active ingredient settling out of solution. Some, but not all, labels will provide advice regarding resuspension. If in doubt, call your pesticide dealer or the product manufacturer to determine if the herbicide contents can be re-dissolved and used, safely and effectively. 


Are Persistent Biocontrol Nematodes a fit for your organic farm?

Organic growers looking for a way to reduce damage to crops from soil-based insects may want to consider entomopathogenic nematodes. Strains of biocontrol nematodes adapted to NY growing conditions with their persistent genes intact to persist across growing seasons (and winter) are available in NY and can be utilized as an integrated tool, along with good cultural practices to suppress the soil insect populations below economic levels throughout the growing season.

Anyone that takes care of a pool knows that inthe last couple of weeks you've probably been fishing out a bunch of brown or brownish silver "bugs".  These "bugs" aremostly Orientalbeetles, June Bugs and Asiatic garden beetles. These beetles, along with Japanese Beetles are the adults of the "whitegrub" complex that affects many lawns, but can also affect many different vegetable and small fruit crops.  Theadults can feed on leaves of plants such as sunflowers, basil, raspberries, carrots,beets and a 100 other different plants. Japanese beetles can also be found in the silks of sweet corn whenpopulations are high.  Although that canbe a problem, the majority of the damage in vegetables comes from the larvae or "white grub" stage feeding on the roots of several different root crops such as sweet potato, carrots and even Irish potatoes. Their long narrow tunnels can cause many roots to be unmarketable.  I dusted off an old article written by former Cornell Cooperative Extension Vegetable Specialist Amy Ivy on how to identify the different beetles and grubs that might be lurking in your fields, lawn and pool

Strategies for Dealing with Pesky Perennial Weeds

Perennial weeds can be particularly difficult to manage in the apple orchard. These plants are defined as being able to live for more than two years, which is due to their abilities to produce large root systems or other underground storage structures, such as bulbs, tubers, and rhizomes. These structures facilitate the spread of perennials in orchards, although many species also produce seed that support dispersal.

Marssonina Leaf Blotch of Apple - A Growing Problem in South-Eastern New York

Excessive rain in New York and the rest of the Eastern US experienced in the second half of both the 2017 and 2018 growing seasons favored the development of Marssonina Leaf Blotch (MLB), a disease caused by Marssonina coronaria (sexual stage Diplocarpon mali). In early September 2017, in the lower-Hudson Valley and south NY we found MLB late in the summer in more than several apple orchards on Mutsu, Honeycrisp, NY-1 (SnapDragon), NY-2 (RubyFrost), Gala, Red Delicious, Golden Delicious, Pristine, Grimes Golden, Northern Spy, Stayman Winesap, Tompkins King, and others. The alarming outcome was defoliation of lower part of the tree crowns, especially where moisture due to heavy dew or sprinkler irrigation was present up until midday.

The CCE Apple Decline Survey Has Been Extended Through the Summer of 2018

Cornell Extension Specialists are being asked with increasing frequency to investigate both chronic decline and rapid collapse of apple trees in young, high-density plantings in all regions of New York State.  Symptoms of chronic decline can include poor growth, off color foliage, and a generally unthrifty appearance that worsens over several years.  The death of an (apparently) previously healthy tree over the course of just a few weeks has been termed Rapid Apple Decline (RAD).  While the symptoms of chronic decline are subtler in some cases, RAD is eye-catching.  Afflicted trees appear to "burn up" mid-summer after having set and sized a normal crop load.  RAD may be a subset of the chronic decline condition or a completely different problem; causation is unknown at this time.

Early weed control is a critical component of establishing a new planting. Newly planted fruit trees compete poorly against fast growing weeds for water and nutrients. This competition can severely limit a new block's growth, which can ultimately reduce potential yields in the third year by 50 percent. Weeds also harbor insects and diseases, provide habitat for rodents, and can serve as hosts for viruses, further complicating effective orchard management.

Bird Damage in Tree Fruits

Anne Mills, Field Technician
Eastern New York Commercial Horticulture

Last Modified: February 27, 2017

Frugivorous birds impose significant costs on tree fruit growers through direct consumption of fruit and
grower efforts to manage birds.We documented factors that influenced tree fruit bird damage from 2012
through 2014 with a coordinated field study in Michigan, New York, and Washington. For sweet cherries,
percent bird damage was higher in 2012 compared to 2013 and 2014, in Michigan and New York
compared toWashington, and in blocks with more edges adjacent to non-sweet cherry land-cover types.
These patterns appeared to be associated with fruit abundance patterns; 2012 was a particularly lowyield
year for tree fruits in Michigan and New York and percent bird damage was high. In addition,
percent bird damage to sweet and tart cherries in Michigan was higher in landscapes with low to
moderate forest cover compared to higher forest cover landscapes. 'Honeycrisp' apple blocks under
utility wires were marginally more likely to have greater bird damage compared to blocks without wires.
We recommend growers prepare bird management plans that consider the spatial distribution of fruit
and non-fruit areas of the farm. Growers should generally expect to invest more in bird management in
low-yield years, in blocks isolated from other blocks of the same crop, and in blocks where trees can
provide entry to the crop for frugivorous birds.

White Rot Fact Sheet

White Rot Fact Sheet

White rot is a worldwide problem in allium production, and has resurfaced in the New York garlic industry after a long period of eradication. Positive samples were collected in 2016 from the Hudson Valley, Central and Western New York, indicating that the disease is widespread. As with other soilborne diseases, white rot can be persistent and devastating. However, careful management can reduce inoculum, and because the disease is spread by seed and soil, it is also possible to prevent its spread into uninfested fields.

White Rot, Sclerotinia cepivorum, decimated the onion industry in New York in the 1930's before being eradicated through careful management. More recently, in 2003, it infected 10,000 acres of garlic in California, leading to the abandonment of some garlic fields and adoption of strict containment rules. White rot has been confirmed in Northeastern states over the last decade as well, with New York being one of the last to discover the disease.  It is now confirmed in the ENYCHP region.  Learn more here.

Feasibility of Reducing Slug Damage in Cabbage

Feasibility of Reducing Slug Damage in Cabbage

Slugs are an increasing threat to cabbage production: The board of the New York Cabbage Research and Development Program made slug control one of their highest research priorities for the first time in 2009. Slugs are considered a sporadic pest in cabbage and are favored by cool and moist conditions, especially where crop residues are left on the soil surface. In conventional production of cabbage, slugs tend to be a problem later in the growing season along tree lines and hedgerows and in weedy patches within the field. Slugs leave large holes in the leaves with the veins intact, and can be a contaminant in the heads when they squeeze between the leaves. During the cool wet growing season of 2009, slug contaminants were the cause of several rejected loads of cabbage in New York. It is predicted that the frequency of slug problems in cabbage will increase, because more cabbage is being grown in rotation following field corn. The newer varieties of field corn are Bt-tolerant and have tougher stalks that take longer to break down, thus, these fields have more crop residue and are more favorable for slugs. It is worthwhile to investigate whether there are cost effective means for growers to manage sporadic infestations of slugs in cabbage.

It is important to emphasize that "exploring" is in the present tense. In New York, we are just beginning to delve into the fascinating relationship between nitrogen, plant spacing and bacterial diseases of onions. Our preliminary results suggest that reduced soil nitrogen and tighter plant spacing results in less bacterial decay. In this article, we report preliminary findings from exploratory studies and the observations that lead to these trials. We stress that we are not making recommendations at this time. However, we are hopeful that further studies will lead to specific recommendations.

Spotted Wing Drosophila in Tomatoes

Although this new pest in gaining attention from berry growers, it is also a threat to tomatoes.  Spotted wing Drosophila (SWD) lays eggs in ripe or maturing fruit with a rear-end that favors a miniature hack-saw. The eggs, which have creepy breathing tubes, hatch out into nasty worms that feed inside the fruit creating a liquefied mass. Reports on tomatoes mention organic, heirloom and high tunnel crops. A common theme to these observations is that insecticides are generally absent. SWD has been reported in 2012 throughout the state, so far in traps and fruit plantings (see map courtesy of Hudson Valley Fruit Program). Likely there are unreported cases of infested tomatoes. 

Cranberry and Cherry Fruit Worm

Cranberry and Cherry Fruit Worm

A number of growers have been calling with a question about blueberry clusters strung together with webbing or frass or both. Most people cannot find a larvae (although they are there!), but are alarmed with picker complaints. The pest in question is fruit worm either cranberry or cherry. Both insects have very similar life cycles and the damage is similar, but the chemical control materials differ slightly, so it will be important to be able to differentiate. 


The adult moths lay their eggs in late May and early June at the base of the newly set fruit. Larvae of both
species attack green fruit. There are sex pheromones  available for both pests and monitoring should begin in late April to optimize spray timing. Usually two sprays are necessary the first at petal fall and the second 10 days later. Organically approved materials include Entrust and Dipel DF. Other materials include Azasol, or Molt-X, Sevin, Malathion, Imidan, Esteem and Delegate, among others.

Designing a Better Sprayer for Pesticide Application in Strawberries

Laura McDermott, Team Leader, Small Fruit and Vegetable Specialist
Eastern New York Commercial Horticulture

Last Modified: April 2, 2012

Strawberry growers using conventional boom sprayers find it difficult to obtain good disease and insect control due to poor pesticide coverage on the undersides of leaves, on the lower leaves, and on the fruit when the strawberry plant is in full canopy. Inadequate crop protectant coverage results in higher levels of disease and insect activity translating to consumer rejection of poor quality fruit and lower overall profitability of the planting.

This project allowed an opportunity to work with strawberries: a high value crop with a low, 3-dimensional canopy. Strawberry diseases are a big concern for growers, so adequate spray coverage is important; better coverage would allow growers to make fewer applications of fungicides during the growing season.

Greenhouse Cucumber Variety Trial (2011)

The unheated greenhouse, or high tunnel, offers a vertical production environment suitable for crops such as indeterminate tomatoes and cucumbers. As it is a soil based system however, and passively heated, greenhouse cucumbers must be transplanted later in the spring than tomatoes, due to their intolerance for low root zone temperatures. However, cucumbers can provide good returns when grown in a high tunnel, given consistent pest control and matching variety performance with market demand. A variety trial of four greenhouse cucumbers was established in a cooperating high tunnel in the spring of 2011.

Stop the Rot! - Using Cultural Practices to Manage Bacterial Diseases of Onion

Stop the Rot! - Using Cultural Practices to Manage Bacterial Diseases of Onion

Narrow plant spacing reduced bacterial bulb decay by 53 to 64%
Do you know how easy this is? A simple modification to adjust your planting configuration is all it would take to drastically reduce losses from bacterial bulb decay. Our studies showed that when plant spacing was reduced from 6 or 8 inches to 4 inches with 3 or 4 rows per 3-foot plastic mulch bed (row spacing: 4 rows = 6 inch; 3 rows = 8 inch), this provided 53 to 64% control of bacterial bulb decay at harvest (Table 1). Marketable yield also increased by 1.4 to 2.4 times, representing an increased net economic return of $43 to $258 per 100 feet of bed, due to increased weight of marketable jumbo-sized bulbs (Table 1). We learned that wide plant spacing produces big bushy plants with more leaves, thicker necks, delayed maturity and bigger bulbs. Unfortunately, it was these bigger bulbs that rotted! By narrowing plant spacing, we got fewer colossal-sized bulbs, which we more than made up for by having significantly more healthy jumbo-sized bulbs to market (Table 1).

Alternatives to black plastic reduced bacterial bulb decay by 59 to 75%
This is also a very simple and easy modification for small-scale growers producing onions on plastic mulch to make to their cultural practices that could go a very long way towards reducing bacterial bulb decay. Our studies showed that reflective silver mulch, biodegradable black plastic and bare ground had significantly 1.8 to 2.8 times higher marketable yield than black plastic (Table 2). Reflective silver and biodegradable black plastics had significantly 3.7 and 3.6 times, respectively, higher jumbo weight than black plastic, which resulted in an increased net return of $96 to $215 per 100 feet of bed compared to black plastic (Table 2). All of the alternatives to black plastic had significantly lower soil temperatures compared to the black plastic; we suspect that the higher temperatures of the black plastic are more favorable for development of bacterial diseases.

Fall Application of Dual Magnum for Yellow Nutsedge Control in Muck Onions

Fall Application of Dual Magnum for Yellow Nutsedge Control in Muck Onions

Yellow nutsedge (Cyperus esculentus L.) pressure is very high in certain muck areas where onions are grown. It appears to have become more of a problem in recent years. Onion growers and chemical company representatives believe that applying Dual Magnum, active ingredient metalochlor, in the fall can significantly reduce nutsedge pressure the following spring. However, weed scientists across the country do not believe that fall applications of metalochlor would have any effect on nutsedge populations the following spring, because the dissipation of metolachlor, is relatively rapid, 4-7 weeks in the northern United States. Dual Magnum is labeled as a fall application in field corn and soybeans only in Iowa, Minnesota, Minnesota, North Dakota, South Dakota and Wisconsin. For this use, there are restrictions on the label that state the date after which Dual Magnum may be applied, that soil temperature in the top 4 inches must consistently be 55°F and lower, and that tillage following incorporation must not exceed the 2-3 inch depth of incorporation.
