Problems solved by technology

[0007] At present, the price of fluorourea is high, it is difficult to promote it in a large area, and it can only be limited to economic crops with high added value
Phoxim is a high-efficiency, low-toxic, broad-spectrum organophosphorus insecticide. It has stomach poisoning and contact killing effects, fast knockdown speed and short duration. It is mainly used to control grain, cotton, vegetables, A variety of pests on fruit trees and other crops, soil, storage, sanitation and other pests, and parasites inside and outside poultry, etc. It is one of the few excellent varieties that can replace highly toxic organophosphates, but it has the persistence of organophosphate insecticides. Short potency and low activity against older Lepidoptera larvae
Therefore, the use of a single agent cannot achieve the best control effect on pests

Embodiment 1

[0026] Weigh 2 grams of fluorourea, 30 grams of phoxim, 5 grams of calcium dodecylbenzenesulfonate, 2 grams of phenethylphenol polyoxyethylene ether, and add the remaining xylene to a total of 100 grams. The raw materials are well measured, prepared according to the conventional emulsifiable concentrate preparation method, and prepared into 32% fluorourea·octyl emulsifiable concentrate.

[0027] The results of the field efficacy test are as follows:

[0028] The results of the field efficacy test for the control of rice leaf rollers are as follows:

[0029]

[0030] As can be seen from the results in the above table, the compound composition of fluoride and phoxim has the following advantages compared with the two single agents:

[0031] (1) The 2, 5, and 10-day control effects on rice leaf rollers are significantly improved, and the synergistic effect is obvious,

[0032] (2) The compound preparation enhances the quick-acting property and prolongs the lasting effect.

Embodiment 2

[0034] Take 0.2 grams of fluorourea, 5 grams of phoxim, 5 grams of calcium dodecylbenzenesulfonate, 5 grams of phenethylphenol polyoxyethylene ether, add solvent oil and additives to the remaining amount to a total of 100 grams, press Prepare and mix by conventional method to form 5.2% fluoride·phoxim emulsifiable concentrate.

Embodiment 3

[0036] Take 5 grams of fluorourea, 4 grams of phoxim, 10 grams of calcium dodecylbenzenesulfonate, and 20 grams of phenylethylphenol polyoxyethylene ether, and prepare 45% fluorourea·phoxim emulsifiable concentrate.

Abstract

The invention relates to a insecticidal composition which comprises fluorine acyl urea and organophosphorus and the application thereof, especially a high efficiency and low toxicity compound insecticide which comprises fluorine acyl urea and phoxim, the basic component of which is 0.1%-20% of fluorine acyl urea and 5%-50% of phoxim, other components are accessory ingredient and menstruum. The advantages of the composition is that the composition has relatively high synergetic effect, lowers application cost and toxicity, expands the insecticidal spectrum, accelerates the injurious insect knockdown speed, prevents and delays the resistance to agricultural chemical of injurious insect, and the composition can prevent lepidopterous pests on crops, fruit tree, and vegetables, and the like, especially prevent rice stem borer, fruit borer, cotton bollworm, etc; the effect of the composition is obviously better than simple dosage.

Description

technical field [0001] The invention relates to an insecticidal composition and its application, in particular to a synergistic insecticidal composition of fluoride and phoxim and its application. Background technique [0002] Fluorourea (novaluron), chemical name 1-[3-fluoro-4-(1,1,2-trifluoro-2-(trifluoromethoxyethoxy)phenyl]-3-(2,6 -difluorobenzoyl)urea, developed by Israel Makhteshim Chemical Co., Ltd., CAS No. 116714-46-6. [0003] Structural formula: [0004] [0005] Fluoride is a benzoylurea insecticide, an insect growth regulator, and a chitin synthesis inhibitor. It can be applied to various agricultural and horticultural crops such as cotton, soybean, corn, fruit trees, and vegetables. It is highly effective against many pests, such as cotton bollworm, borer, leaf tortrix, diamondback moth, cabbage caterpillar, pine caterpillar, whitefly, thrips, etc. [0006] This variety has broad spectrum, high efficiency, low toxicity, low residue, is friendly to the env...
