Effect test

Embodiment 1

[0039] Example 1: ZJ4042 mixed with spinosad

[0040] Table 1 Combined synergistic effect of ZJ4042 and spinosyn on Plutella xylostella

[0041] deal with

[0042] Table 2 Combined synergistic effect of ZJ4042 and spinosad on Spodoptera exigua

[0043] deal with

[0044]

[0045] It can be seen from Tables 1 and 2 of the test results that the compound composition of spinosad and ZJ4042 has a co-toxicity coefficient greater than 120 in the range of 1-20:30-1 (by weight ratio), and is effective for cabbage. Moth and beet armyworm both showed synergistic effect. The combination of spinosad and ZJ4042 is reasonable and feasible.

Embodiment 2

[0046] Embodiment 2 (20% spinosyn ZJ4042 suspension concentrate)

[0047] Spinosad 18%, ZJ4042 2%, emulsifier 1601# (styrylphenol polyoxyethylene polyoxypropylene ether) 10%, dispersant SOPA-2704 4%, bentonite 2%, xanthan gum 0.1%, organic 0.4% silicon defoamer, 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 prepared after high-shear mixing to prepare a 20% spinosad ZJ4042 suspension.

[0048] This embodiment 2 is applied to control Plutella xylostella. Spray 20% spinosad ZJ4042 suspending agent at 10 g / mu in the peak stage of Plutella xylostella larvae and spray evenly with water, and the control effects are 95.6% and 97.2% after 3 days and 7 days after spraying. Control a single dose of 2.5% spinosad suspension concentrate (application rate is 50 g / mu) and 20% ZJ4042 suspension concentrate (application rate is 10 g / mu) in the same way, and the control effects after 3...

Embodiment 3

[0049] Embodiment 3 (20% spinosyn ZJ4042 emulsifiable concentrate)

[0050] Spinosyn 18%, ZJ4042 2%, calcium dodecylbenzenesulfonate 6%, tristyrylphenol polyoxyethylene ether 6%, NMP 8%, and the balance is xylene. Mix the above formula in proportion and stir evenly.

[0051] This embodiment 3 is applied to control Spodoptera litura. 20% spinosad · ZJ4042 EC was sprayed evenly with water at 10 g / mu in the peak period of Spodoptera litura larvae occurrence, and the control effects were 93.7% and 95.9% 3 days and 7 days after spraying. Control a single dose of 2.5% spinosad suspension concentrate (application rate is 50 g / mu) and 20% ZJ4042 suspension concentrate (application rate is 10 g / mu) in the same way, and the control effects after 3 days of application are respectively 75.7%, 86.3%, 7 days after the drug control effect was 78.3%, 87.5%. After mixing spinosad and ZJ4042, the synergistic effect is obvious, the control effect is better than single dose, the quick-acting a...

Abstract

The invention discloses an insecticidal composition for agricultural insects, which contains two active ingredients: the first active ingredient is spinosad, 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 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, in particular to a method composed of spinosyn and 3-chloro-N 1 -(2-Methyl-4-heptafluoroisopropylphenyl)-N 2 -(1-methyl-1-cyanoethyl) phthalamide is a high-efficiency and low-toxicity 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 costs of pestici...
