Embodiment 1

[0021] In order to verify the insecticidal effect of different ratios of chlorantraniliprole and imophos on rice pests, the indoor toxicity test of different ratios of chlorantraniliprole and imophos on rice pests was carried out. Weight percent is made into corresponding concentration, carries out indoor insecticidal test, to measure co-toxicity coefficient, test result is reported as follows now:

[0022] Test method: adopt the dipping feed method, that is, treat 20 4-5 instar Chilo suppressalis larvae, set three repetitions, and soak in clean water as a control. Cut the rice stalks at the tillering stage that have not been applied with pesticides into 4-5 cm long pieces, put them into the above-prepared medicinal solution, soak for one minute, take them out, use absorbent paper to absorb the medicinal solution on the surface of the rice stalks, and put them in In a bowl, put 10 larvae of the 5th instar Chilo borer, cover with a layer of plastic wrap, perforate a few small h...

Embodiment 2

[0027] 26% Chlorantraniliprole Imidophos EC

[0028] Chlorantraniliprole 1%

[0029] imophos 25%

[0030] Nongru 500 (emulsifier) ​​11.5%

[0031] Cyclohexanone (solvent) 6%

[0032] Toluene (solvent) 15.5%

[0033] Xylene (solvent) Make up to 100%.

[0034] Weigh the ingredients according to the above weight ratio, start the mixer, add chlorantraniliprole, imophos, and solvent in turn, after stirring and mixing evenly, add emulsifier, and stir for 40 minutes to obtain the product, and use this product for rice distilling The field efficacy test of Chilo borer has achieved a good control effect, with a control effect of 98.7%.

Abstract

The invention discloses a compound pesticide containing chlorantraniliprole and phosmet and a preparation method thereof. The compound pesticide contains effective ingredients of chlorantraniliprole and phosmet, and an additive is assisted. In the preparation method, the chlorantraniliprole and the phosmet are compounded, and the preparation method has the advantages of simple production equipment, no three-waste discharge, short technical flow, low processing cost and the like. Meanwhile, the compound pesticide has the advantages of wide pesticidal spectrum, long effect lasting period, high pesticidal speed, strong knocking-down capability, obvious synergism, good environmental compatibility and little pesticide cost and is an ideal new compound pesticide variety for preventing and controlling pests of cotton and rice, and pest resistance development can be delayed.

Description

technical field [0001] The invention relates to a pesticide composition for controlling rice and cotton pests, in particular to a compound pesticide composition containing chlorantraniliprole and imophos and a preparation method thereof. Background technique [0002] In today's agricultural production, due to the single and continuous use of a certain chemical pesticide, the problem of pesticide resistance will become increasingly serious, and many pesticides have to be stopped in some areas due to resistance problems. For example, cotton bollworm, Spodoptera litura, Rice leaf roller, Chilo borer, etc. are the main pests of cotton and rice in my country, especially in the Yangtze River Basin. In the middle and later stages of cotton, a large number of buds will fall off after being damaged, and the physiological imbalance of the plant will lead to crazy growth and serious loss of yield. In addition to causing white ears in the middle and late stages of rice, it also causes ...
