摘要: Field workers hand harvesting, stripping, thinning, disbudding, pruning, and pinching crops come into contact with toxic organophosphate residues on foliage. These inhibit Cholinesterase activity, causing dizziness, pinpoint pupils, nausea, headache, other symptoms which, if severe enough, lead to hospitalization and/or loss of work. To reduce these hazards, the California Department Agriculture in 1971 established reentry intervals for 16 organophosphate1 insecticides. This list has been expanded over last eight years include 21 insecticides used vine tree fruits as indicated Table I.
