Embodiment 1

[0039] Example 1: Example of mixing ZJ4042 with chlorfluazuron

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

[0041] deal with

[0042] Chlorfluazuron: ZJ4042

[0043]Table 2 The combined synergistic effect of ZJ4042 and chlorfluazuron on the cabbage beet armyworm Spodoptera exigua

[0044] deal with

[0045] It can be seen from Tables 1 and 2 of the test results that hexazuron and ZJ4042, in the range of 1 to 20:30 to 1 (by weight), have a co-toxicity coefficient greater than 120, and are both effective against Plutella xylostella and Spodoptera oleracea. Shown as a synergistic effect. It is reasonable and feasible to mix chlorfluazuron and ZJ4042.

Embodiment 2

[0046] Example 2 (20% Chlorfluazuron ZJ4042 Suspension Concentrate)

[0047] Chlorfluazuron 18%, ZJ404 22%, emulsifier 1601# (styrene-based phenol 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 then prepared after high-shear mixing to prepare 20% chlorfluazuron·ZJ4042 suspension concentrate.

[0048] This embodiment is applied to control Plutella xylostella. 20% Chlorfluazuron·ZJ4042 suspension was sprayed evenly with water at 10 g / mu in the peak stage of the occurrence of Plutella xylostella larvae, and the control effects were 94.3% and 96.1% after 3 days and 7 days after spraying. Control single dose of 5% chlorfluazuron emulsifiable concentrate (application rate is 30 g / mu) and 20% ZJ4042 suspension concentrate (applicati...

Embodiment 3

[0049] Example 3 (40% Chlorfluazuron ZJ4042 water dispersible granules)

[0050] According to chlorfluazuron 35%, ZJ40425%, sodium lauryl sulfate 6%, polysulfate 4%, sodium chloride 8%, polyethylene glycol 3%, the balance is kaolin. The above formula is dry crushed, granulated, dried and sieved according to the proportion to prepare 40% chlorfluazuron·ZJ4042 water dispersible granules.

[0051] This embodiment is applied to control Spodoptera litura. 40% Chlorfluazuron·ZJ4042 water-dispersible granules were mixed with water and sprayed evenly at 10 g / mu on the peak of Spodoptera litura larvae, and the control effects were 93.5% and 97.2% 3 days and 7 days after spraying. Control single dose of 5% chlorfluazuron emulsifiable concentrate (application rate is 30 g / mu) and 20% ZJ4042 suspension concentrate (application rate is 10 g / mu) are applied in the same way, and the control effects after 3 days are respectively 78.3%, 85.9%, and the control effect 7 days after the drug was...

Abstract

The invention discloses an agricultural insecticidal composition containing two active ingredients, namely chlorfluazuron and 3-chloro-N1-(2-methyl-4-heptafluoroisopropyl phenyl)-N2-(1-methyl-1-cyanoethyl)phthalimide which are in the weight ratio of (1-20): (30-1). The insecticidal composition disclosed by the invention is suitable for preventing and treating destructive insects, such as spodoptera litura, beet armyworm, cabbage caterpillar, diamondback moth 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, in particular to a compound composed of chlorfluazuron 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 pesticides for f...
