Effect test

Embodiment 1

[0039] Embodiment 1: ZJ4042 is mixed with beta-cypermethrin

[0040] Table 1 Combined synergistic effect of ZJ4042 and beta-cypermethrin on Plutella xylostella

[0041]

[0042] Table 2 The combined synergistic effect of ZJ4042 and beta-cypermethrin on the cabbage aphid Lipaphis erysimi

[0043]

[0044] It can be seen from Tables 1 and 2 of the test results that the compounded agricultural insecticidal composition of beta-cypermethrin and ZJ4042 has a co-toxicity coefficient greater than 120 in the range of 1 to 20:30 to 1 (by weight), and is effective against cabbage. Plutella xylostella and aphids both showed synergistic effect. It is reasonable and feasible to mix beta-cypermethrin and ZJ4042.

Embodiment 2

[0045] Embodiment 2 (20% beta-cypermethrin ZJ4042 suspension concentrate)

[0046] Beta-cypermethrin 18%, ZJ404 22%, emulsifier 1601# (styrylphenol polyoxyethylene polyoxypropylene ether) 10%, dispersant SOPA-27044%, bentonite 2%, xanthan gum 0.1%, silicone defoaming 0.4% agent, 5% glycerol, and the balance is deionized water. The above formula is pre-crushed according to the proportion, then added to a sand mill for grinding, and then prepared after high-shear mixing to prepare 20% beta-cypermethrin·ZJ4042 suspending agent.

[0047] This embodiment 2 is applied to control Plutella xylostella. 20% beta-cypermethrin · ZJ4042 suspending agent was sprayed uniformly with water at 10 g / mu in the peak stage of Plutella xylostella larvae, and the control effects were 95.2% and 96.7% after 3 days and 7 days after spraying. Control single agent 4.5% beta-cypermethrin emulsifiable concentrate (application rate is 30 g / mu), 20% ZJ4042 suspension concentrate (application rate is 10 g / mu...

Embodiment 3

[0048] Embodiment 3 (40% beta-cypermethrin ZJ4042 water dispersible granule)

[0049] Beta-cypermethrin 35%, ZJ404 25%, sodium lauryl sulfate 6%, polysulfate 4%, sodium chloride 8%, polyethylene glycol 3%, and the balance is kaolin. Dry pulverize, granulate, dry and sieve the above formula in proportion to prepare 40% beta-cypermethrin·ZJ4042 water-dispersible granules.

[0050] This embodiment 3 is applied to control cabbage aphids. 40% beta-cypermethrin·ZJ4042 water dispersible granules were sprayed uniformly with water at 10 g / mu in the peak period of occurrence of cabbage aphid nymphs, and the control effects were 93.6% and 96.7% 3 days and 7 days after spraying. Control single agent 4.5% beta-cypermethrin emulsifiable concentrate (application rate is 30 g / mu), 20% ZJ4042 suspension concentrate (application rate is 10 g / mu) are sprayed in the same way, and the control effects after 3 days of application are 77.3 %, 85.9%, and the control effects after 7 days were 78.2% a...

Abstract

The invention discloses an insecticidal composition for agricultural insects, which contains two active ingredients: the first active ingredient is beta cypermethrin, the second active ingredient is 3-chlorine-N<1>-(2-methyl-4-heptafluoroisopropyl phenyl)-N<2>-(1-methyl-1-cyano ethyl) phthalic diamide, and the weight ratio of the first active ingredient to the second active ingredient is (1-20):(50-1). The insecticidal composition is suitable for controlling piercing-sucking mouthpart insects and lepidoptera insects, and superior to a single insecticide in quick-acting property and persistent-acting property, the use cost of the insecticide is low, and environmental protection and comprehensive control of the agricultural insects are facilitated.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a method composed of beta-cypermethrin and 3-chloro-N 1 -(2-methyl-4-heptafluoroisopropylphenyl)-N 2 -(1-methyl-1-cyanoethyl) phthalamide is a high-efficiency and low-toxic agricultural insecticide composition and its insecticide. Background technique [0002] The problem of resistance to agricultural pests is a global problem. With the continuation of chemical control of pests, the increase in the use of pesticides, and the unscientific use of pesticides, the resistance of pests is becoming more and more serious, and the types of resistant pests are increasing. Especially the lepidopteran pests that seriously damage agricultural production have a high degree of resistance and relatively fast development of resistance. At the same time, the high-intensity use of pesticides leads to excessive pesticide residues in agricultural products, environmental pollution and increase...
