Application

1,3-dichloropropene is used as soil fumigant nematicide in pre-planting control of most species of nematode in deciduous fruit and nuts, citrus fruit, berry fruit, vines, strawberries, hops, field crops, vegetables, tobacco, beet, pineapples, peanuts, ornamental and flower crops, tree nurseries, etc. Also has secondary insecticidal (soil insects) and fungicidal activity, and, by controlling nematode virus vectors, control is obtained of virus diseases of strawberries, raspberries, tomatoes, hops, etc. Applied at 60–350 lb/a. Phytotoxicity Can be phytotoxic if crops are planted too soon after application. Both isomers are active; the (Z)- isomer is the more effective to nematodes.
