Embodiment 1

[0039] Example 1: Example of mixing ZJ4042 and indoxacarb

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

[0041] deal with

[0042] ZJ4042

[0043] Table 2 Combined synergistic effect of ZJ4042 and indoxacarb on Cnaphalocrocis medinalis

[0044] deal with

[0045] Indoxacarb: ZJ4042

[0046] It can be seen from Tables 1 and 2 of the test results that indoxacarb and ZJ4042, within the range of 1-50:20-1 (by weight ratio), have a co-toxicity coefficient greater than 120, which is effective against cabbage diamondback moth and rice longitudinal roll moth. Leaf borer showed a synergistic effect. The mixing of indoxacarb and ZJ4042 is reasonable and feasible.

Embodiment 2

[0047] Example 2 (20% indoxacarb ZJ4042 suspension concentrate)

[0048] Indoxacarb 18%, ZJ404 22%, emulsifier 1601# (styrylphenol polyoxyethylene polyoxypropylene ether) 10%, dispersant SOPA-27044%, bentonite 2%, xanthan gum 0.1%, organic silicon disinfectant Foaming agent 0.4%, glycerin 5%, 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 20% indoxacarb·ZJ4042 suspension concentrate.

[0049] This embodiment is applied to control Plutella xylostella. 20% indoxacarb·ZJ4042 suspension was sprayed uniformly with water at 10 g / mu in the peak stage of Plutella xylostella larvae, and the control effects were 92.3% and 94.7% after 3 days and 7 days after spraying. Control single dose of 15% indoxacarb SC (15 g / mu) and 20% ZJ4042 SC (10 g / mu) were sprayed in the same way, and the control effects after 3 days were respectively 71.2%, 85.7%, 7 days af...

Embodiment 3

[0050] Example 3 (40% indoxacarb ZJ4042 water dispersible granules)

[0051] According to indoxacarb 35%, ZJ40425%, sodium lauryl sulfate 6%, polysulfate 4%, sodium chloride 8%, polyethylene glycol 3%, the balance is kaolin. Dry pulverize, granulate, dry and sieve the above formula in proportion to prepare 40% indoxacarb·ZJ4042 water-dispersible granules.

[0052] This embodiment is applied to control Spodoptera litura. 40% indoxacarb·ZJ4042 water dispersible granules were sprayed uniformly with water at 10 g / mu at the peak of Spodoptera litura larvae occurrence, and the control effects were 90.2% and 91.7% at 3 days and 7 days after spraying. Control single dose of 15% indoxacarb SC (15 g / mu) and 20% ZJ4042 SC (10 g / mu) were sprayed in the same way, and the control effects after 3 days were respectively 71.7%, 85.1%, 7 days after the drug control effect was 72.9%, 86.4%. After mixing indoxacarb and ZJ4042, the synergistic effect is obvious, the control effect is better tha...

Abstract

The invention discloses an agricultural insecticidal composition containing active ingredients, namely indoxacarb and 3-chloro-N1-(2-methyl-4-heptafluoroisopropyl phenyl)-N2-(1-methyl-1-cyanoethyl)phthalimide which are in the weight ratio of (1-50): (20-1). The insecticidal composition disclosed by the invention is suitable for preventing and treating destructive insects, such as spodoptera litura, beet armyworm, diamondback moth, cnaphalocrocis medinalis and cotton bollworm, of crops. According to the agricultural insecticidal composition, the quick acting performance and effect lasting performance are better than those of single agents, and the dosage and medicating cost of insecticide are reduced, so that the environmental protection and comprehensive treatment on agricultural insects are facilitated.

Description

technical field [0001] The invention belongs to the field of pesticides, and specifically relates to a compound composed of indoxacarb and 3-chloro-N 1 -(2-methyl-4-heptafluoroisopropylphenyl)-N 2 - (1-methyl-1-cyanoethyl) phthalamide compounded high-efficiency and low-toxicity pesticide 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 a rapid 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 pesticide...
