Embodiment 2

[0045] Embodiment 2 (20% chlorpyrifos · ZJ4042 suspension concentrate)

[0046] Chlorpyrifos 18%, ZJ404 22%, emulsifier 1601# (styrylphenol polyoxyethylene polyoxypropylene ether) 10%, dispersant SOPA-27043%, bentonite 2%, xanthan gum 0.1%, silicone defoamer 0.4%, glycerin 5%, 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 prepared after high-shear mixing to prepare a 20% chlorpyrifos·ZJ4042 suspension.

[0047] This embodiment is applied to control Plutella xylostella. 20% chlorpyrifos · ZJ4042 suspension was sprayed uniformly with water at 10 g / mu in the peak stage of the occurrence of Plutella xylostella larvae, and the control effects were 93.9% and 95.3% after 3 days and 7 days after spraying. Control single agent 48% chlorpyrifos emulsifiable concentrate (application rate is 50 g / mu), 20% ZJ4042 suspension concentrate (application rate is 10 g / mu) are applied in the same way,...

[0048] Embodiment 3 (20% chlorpyrifos ZJ4042 emulsifiable concentrate)

[0049] Chlorpyrifos 15%, ZJ404 25%, calcium dodecylbenzenesulfonate 6%, tristyrylphenol polyoxyethylene ether 6%, NMP 8%, and the balance is xylene. Mix the above formula in proportion and stir evenly.

[0050] This embodiment is applied to control Spodoptera litura. 20% chlorpyrifos·ZJ4042 EC was sprayed evenly with water at 10 g / mu at the peak of Spodoptera litura larvae occurrence, and the control effects were 93.7% and 95.9% 3 days and 7 days after spraying. Control single agent 48% chlorpyrifos emulsifiable concentrate (application rate is 50 g / mu), 20% ZJ4042 suspension concentrate (application rate is 10 g / mu) are sprayed in the same way, and the control effect after 3 days of application is 65.7% respectively , 85.1%, and the control effects 7 days after the drug were 68.3%, 86.4%. After mixing chlorpyrifos and ZJ4042, the synergistic effect is obvious, the control effect is better than single ...

Abstract

The invention discloses an insecticidal composition for agricultural insects, which contains two active ingredients: the first active ingredient is chlopyrifos, 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 (1-50):(20-1). The insecticidal composition is suitable for controlling insects such as crop prodenia litura, beet armyworms, plutella xylostella, chilo suppressalis walkers, rice leaf rollers and cotton bollworms, and is superior to a single insecticide in quick-acting property and persistent-acting property; the use amount and the use cost of the insecticide are reduced; and the 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 compound composed of chlorpyrifos 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 increased c...
