Management of insect pests of broccoli, cowpeas, spinach, tomatoes, and peanuts with chemigation by insecticides in oils, and reduction of watermelon virus 2 by chemigated oil
Publication date:
Insect infestations and damage to various crops were effectively controlled with insecticides applied in center-pivot irrigation system. On spinach, the vegetable leaf-miner, Liriomyza sativae, was controlled with diazinon, and Lygus bugs, Lygus spp., were controlled with carbaryl. On tomatoes, Colorado potato beetles, Leptinotarsa decemlineata, and tomato fruitworms, Heliothis spp., were controlled with permethrin, and the two spotted spider mite, Tetranychus urticae, was controlled with propargite. On broccoli, the cabbage caterpillar complex, Trichoplusia ni, Pieris rapae, and Plutella xylostella, was controlled with fenvalerate. On cowpwas, the cowpea curculio, Chalcodermus aeneus, was controlled with permethrin, fenvalerate, and encapsuulated methyl parathion. On peanusts, thrips, Frankliniella spp., and corn earwarms, H. zea, were controlled with carbaryl;the corn earworm was controlled with thiodicarb, and leafhoppers (Cicadellidae) were controlled chlorpyriphos. Spread of watermelon mosaic virus 2 was reduced 50 percent by chemigation with Suntec 7N oil.
