Anti-mite composition

Abstract

The invention belongs to the technical field of compounded pesticides, and concretely relates to an anti-mite composition. The anti-mite composition comprises the following raw materials in percent by weight: 0.1-20% of spirodiclofen, 0.1-60% of fluazinam, and the balance an auxiliary agent. The composition, which is formed by combining the two main ingredients according to the above ratio, is applicable to control multiple pest mites at the same time, and is applicable to kill multiple pest mites. Compared with a conventional manner of using multiple drugs to kill mite, the employed drug kind is reduced, drug usage cost is reduced, environment pollution is reduced, and the disclosed anti-mite composition possesses extremely good persistent period. Harmful mites are prevented from generating drug resistance by mixing the above pesticides, and the service life of different kinds of pesticides is prolonged.

Description

technical field

[0001] The invention belongs to the technical field of compound pesticides, in particular to an acaricide composition. Background technique

[0002] There are many generations of harmful mites and strong reproductive ability. Under suitable temperature and humidity conditions, the number of harmful mites can rapidly double in a short period of time, so it is easy to develop resistance to acaricides. serious damage to crops. At present, in terms of pest control, most of them still adopt the method of batch control with multiple drugs, but this method of batch control with multiple drugs greatly increases the cost and difficulty of control. In order to prevent and control various harmful mites that are becoming more and more serious, countries around the world are constantly developing new types of acaricides. In the process of development and application of acaricides, delaying the resistance or cross-resistance of harmful mites is the key factor to prolong t...

Examples

Embodiment 1

[0039] An acaricidal composition, the raw material components in parts by weight are: 50 parts of fluazinam, 10 parts of spirodiclofen, 10 parts of sodium lignosulfonate, 0.1 part of calcium dodecylbenzenesulfonate, 4 parts of diol, 0.1 part of xanthan gum, 2 parts of silicone oil, and 100 parts of xylene are used to prepare a suspending agent according to a conventional method.

[0040] The compound pesticide prepared above has a control effect of 99.7% on citrus spider mite.

Embodiment 2

[0042] An acaricidal composition, the raw material components in parts by weight are: 0.1 part of fluazinam, 0.5 part of spirodiclofen, 30 parts of calcium lignosulfonate, 30 parts of alkylphenol polyoxyethylene ether, glycerin 0.1 part of alcohol and 100 parts of methanol were added, and an aqueous emulsion was prepared according to a conventional method.

[0043] The above-mentioned prepared pesticides are compounded to achieve a control effect of 99% on citrus red spider mites.

Embodiment 3

[0045] An acaricidal composition, the raw material components of which are calculated in parts by weight: 40 parts of fluazinam, 4 parts of spirodiclofen, 8 parts of polycarboxylate, 5 parts of polyoxyethylene fatty acid ester, dodecyl 10 parts of sodium sulfate, 6 parts of bentonite, 4 parts of magnesium aluminum silicate, 2 parts of silicone oil, and 100 parts of white carbon black are used to prepare water-dispersible granules according to conventional methods.

[0046] The pesticides prepared above are compounded, and the control effect on Tetranychus cinnabarinus can reach 95.5%.
