[0065] Example 68, 69 microcapsule suspension

[0066] Mix cyclopronil, active ingredient B, polymer capsule wall material, and solvent to dissolve into a uniform oil phase. Under shearing conditions, add the oil phase to the aqueous phase solution containing emulsifier, pH regulator, and dispersant In the process, the balance is supplemented with deionized water, and the two materials react at the oil-water interface to form a polymer capsule wall to make a well-dispersed microcapsule suspension product of the composition of the present invention. See Table 7 for details.

Abstract

The invention discloses an insecticidal composition containing dicyclanil and a carbamate compound. The insecticidal composition contains an active component A and an active component with a weight ratio of 1:70-50:1, wherein the active component A is dicyclanil, and the active component B is any one compound selected from the following compounds: isoprocarb, metolcarb, indoxacarb and carbaryl. The composition of the invention has synergy effect on multiple insects harmful to agriculture production, helps to reduce pesticide use amount and reduce residual quantity of pesticides on crops, is safe to people and livestock, good in environmental compatibility and insusceptible to arousing drug resistance in the insects.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of an insecticidal composition containing cyclopronil and carbamates on crop pests. Background technique [0002] Dicyclanil chemical name: 4,6-diamino-2-cyclopropylaminopyrimidine-5-carbonitrile, molecular formula: C 8 h 10 N 6 . Cyclopronil interferes with insect shedding and, when absorbed by the insect's reproductive system, prevents larvae from pupating or becoming worms. [0003] Isoprocarb (isoprocarb) chemical name: o-isopropylphenylmethyl carbamate, molecular formula: C 11 h 15 NO 2 . Isoprocarb is a carbamate insecticide, which mainly inhibits acetylcholinesterase on insects, causing paralysis to death of insects. [0004] Metolcarb (metolcarb) chemical name: m-tolyl-N-methylcarbamate, molecular formula: C 9 h 11 NO 2 . Meprocarb has contact killing and fumigation effects, strong knockdown power, short duration of effect, generally only 3-4 ...
