Potatoes

Potatoes have many serious insect and disease pests. Late blight can be a devastating disease, capable of completely destroying an unprotected crop within 3 weeks in wet weather, and rotting the tubers. Late blight was the major cause of the Irish Potato Famine. It also affects tomatoes. New, more virulent strains of late blight fungus began showing up 20 years ago and the disease has been harder to predict and control ever since. Early blight is a common fungal disease on both potatoes and tomatoes which survives over-winter in the soil. Colorado potato beetles can cause serious defoliation if crops are not rotated up to a quarter mile from where they, tomatoes or eggplant were previously planted. They can rapidly become resistant to commonly used insecticides. Tiny, sucking leafhoppers move up from the south each June on weather systems, and can cause severe leaf burn and yield reduction. Aphids can also be a production problem as well as carrying viral diseases that can affect potatoes grown from saved seed.
Interseeding Summer Cover Crops Between Vegetable Beds, Trial Results
Chuck Bornt, Team Leader, Extension Vegetable Specialist
Eastern New York Commercial Horticulture
Managing weeds between vegetable beds remains an on-going issue for vegetable growers, both organic and conventional. It is common practice for vegetable growers to transplant crops into beds covered with black plastic mulch. This strategy provides excellent weed control in the planted row but leaves soil between beds exposed and vulnerable to erosion, compaction, and weed growth. Conventional growers often use herbicides for weed control, but herbicides applied at crop establishment do not provide season long control. Organic growers can mow or use tillage to control weeds, but this can be difficult between beds with plastic mulch and the soil is continuously disturbed decreasing soil health over time. Planting cover crops to protect and improve soil health is not new and the potential benefits of cover crops are well known.

The CPB is known for its ability to quickly develop resistance to insecticides. There are alternatives to insecticides for managing CPB, but for growers with large fields and a limited ability to rotate fields, insecticides remain key.
O-zone Injury on Vegetables
Crystal Stewart-Courtens, Extension Vegetable Specialist
Eastern New York Commercial Horticulture

Hot, humid weather with stagnant air masses may lead to ozone damage on crops. Ozone warnings were recently issued for much of New York. These warnings are intended for people with respiratory problems and let them know they should limit their outdoor activity and try to stay as much as possible in air-conditioned locations. These warning are also a good indicator that ozone damage may occur in plants.
Nightshade Management Reduces Crop Loss

Getting the Most Out of Every Pass - Calibrating Airblast Sprayers for Best Results
June 29 - June 30, 2022
University of New Hampshire Extension Field Specialist Emeritus, George Hamilton will demonstrate the importance of and best techniques to calibrate air blast sprayers. Proper calibration will ensure effective, efficient, economical and legal spraying. Inadequate spray coverage is usually the cause of poor spray efficacy and additional spray applications. Overuse of some sprays results in unhealthy residues and can lead to fines.
Calibration should be done several times each season, or when you incorporate any new equipment or repairs - from the tractor to the nozzle. Join us for a refresher or send new employees for training. This workshop is open for any grower that relies on an airblast sprayer to deliver plant protectants to fruit or vegetable crops.
