Embodiment 2

[0035] Preparation method example 2: 40% chlorothialine·spirotetramat water-dispersible granules.

[0036]

[0037]

[0038] The above formula is dry crushed, granulated, dried and sieved according to the proportion to prepare 40% chlorothiazolin·spirotetramat water dispersible granules.

Embodiment 3

[0039] Preparation method example 3: 20% chlorothialine·spirotetramat suspension concentrate.

[0040]

[0041] The above-mentioned materials are pre-crushed in proportion, and then added to a sand mill for grinding, and then prepared after high-shear mixing to prepare a 20% chlorothialine·spirotetramat suspension concentrate.

Embodiment 4

[0042] Preparation method example 4: 18% chlorothialine·spirotetramat emulsion in water.

[0043]

[0044]

[0045] Dissolve the original drug, solvent, and emulsifier in the above formula into a uniform oil phase; mix the water-soluble components in the above formula with deionized water to obtain a water phase; under high-speed stirring, mix the oil phase and water phase to obtain 18% Chlorthialine · spirotetramat emulsion in water.

[0046] Field Efficacy Test Example 1: Field test of controlling tomato Bemisia tabaci.

[0047] The test site is located in Laokeng Village, Renshan Town, Huidong County, Huizhou City, Guangdong Province. The test time is May 2013, and the spray method is used. Using 10% chlorothialine wettable powder and 22.4% spirotetramat suspension concentrate as control agents, the test set up 5 drug treatments in total, each treatment was repeated 4 times, and the worm mouth base was investigated before application, and 3 days after application 1....

Abstract

The invention discloses a pesticide composition containing imidaclothiz and spirotetramat. The pesticide composition is characterized in that the active ingredients are imidaclothiz and spirotetramat in a weight ratio of (1 to 10)-(10 to 1); the rest of the ingredients are common auxiliary ingredients of pesticide preparations; the total weight percent of imidaclothiz and spirotetramat in the herbicide composition is 4-90%. The pesticide composition has obvious synergistic effects, has obviously better control effects than single agents used independently, also reduces the pesticide usage amount and the pesticide residues on crops, reduces environmental pollution and delays the pesticide resistance of diseases and insect pests.

Description

technical field [0001] The invention relates to a pesticide composition and its application field, in particular to a pesticide composition with chlorothialine and spirotetramat as active ingredients, which is mainly used for preventing and treating piercing-sucking mouthparts pests on crops. Background technique [0002] The problem of resistance to agricultural pests is a global problem and has always been a key topic of concern to agricultural science and technology workers. With the continuation of chemical pest control year after year, 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. 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 farmers, which is not conducive to the sustainable development of agricultu...
