A detailed blog about moth activity and statewide distribution maps has been posted at https://sites.aces.edu/group/commhort/blog/Lists/Posts/Post.aspx?ID=262. Research plots at Clanton, Cullman, and Brewton all have heavy caterpillar pressure at present. Several overlapping generations of beet armyworms, fall armyworms, soybean loopers, tomato fruitworms, and tomato hornworms have been feeding on late-planted tomatoes that almost require weekly application of insecticides. We also had plenty of aphid issues this year – sugarcane aphids first showed up in the sorghum trap crop at all locations (including producer fields) followed by the potato aphids on late-planted tomatoes. I recommend cole crop producers to closely monitor their crops for aphids and implement control measures before an aphid outbreak. For more information about cool season insect pests, refer to the new Extension bulletin ANR-2241, Insect Pest Scouting for Crucifer Crops.

Complete insecticide recommendations can be found in the SE Vegetable Crop Handbook. Organic pest management recommendations can be found in the Alternative Vegetable IPM Slide Chart which is a handy tool for small producers and backyard gardeners. Also, visit the insect pest and natural enemy photo album on our Facebook page.
