Problems solved by technology

[0006] In recent years, rice planthoppers, thrips and other piercing-sucking pests have occurred in a large area in rice planting areas in southern my country. Farmers generally use imidacloprid, acetamiprid and other drugs to prevent and control rice planthoppers, thrips and other piercing-sucking pests. The pests have developed serious drug resistance to the above-mentioned drugs, and the pollution to the environment has also tended to be serious.

Embodiment 1

[0023] Example 1: 10% thiacloprid·butene fipronil water dispersible granules

[0024] Prepare 10% thiacloprid·butene fipronil water dispersible granules according to the following proportions, spray evenly at 1500 times to control rice planthoppers, and compare the control effects on 3 days, 5 days and 7 days after application.

[0025] Weigh 5g of thiacloprid technical material, 5g of butylene fipronil, 1g of saponin powder, 5g of sodium lignosulfonate, 5g of ammonium sulfate, and 20g of light calcium carbonate, and mix them according to the general method. Mix the parent powder with 2g of polyvinylpyrrolidone evenly, then supplement it with kaolin to 100g, then granulate, dry and sieve to obtain 10% thiacloprid-butene-fipronil water dispersion Granules. After testing, the active ingredient content is 10%, the suspension rate is ≥75%, the moisture content is ≤2.5%, the pH is 7.1, the particle size range (225-800um) is ≥98%, the dispersibility is ≥85%, the wetting time is ≤90...

Embodiment 2

[0026] Example 2: 20% thiacloprid·butene fipronil water dispersible granules

[0027] Prepare 20% thiacloprid·butene fipronil water dispersible granules according to the following proportions, spray evenly at 1500 times to control rice planthoppers, and compare the control effects on 3 days, 5 days and 7 days after spraying.

[0028] Weigh 5 g of thiacloprid technical material, 15 g of butylene fipronil, 3 g of pull-off powder, 5 g of carboxymethyl cellulose, 2 g of ammonium bicarbonate, and 25 g of white carbon black, mix them according to the general method, stir evenly, and Mix the parent powder with 3g of polyethylene glycol evenly, then supplement it with soluble starch to 100g, then granulate, dry and sieve to obtain 20% thiacloprid-butene-fipronil Water-dispersible granules. After testing, the active ingredient content is 20%, the suspension rate is ≥75%, the water content is ≤2.5%, the pH is 7.1, the particle size range (225-800um) is ≥98%, the dispersibility is ≥85%,...

Embodiment 3

[0029] Example 3: 28% thiacloprid·butene fipronil water dispersible granules

[0030] Prepare 28% thiacloprid·butene fipronil water dispersible granules according to the following proportions, spray evenly at 1500 times to control rice planthoppers, and compare the control effects on 3 days, 5 days and 7 days after spraying.

[0031] The original drug thiacloprid 8g, butene fipronil 20g, sodium lauryl sulfate 5g, pull open powder 1g, ammonium sulfate 4g, polyethylene glycol 1g, kaolin 61g, fully stirred and mixed, ground and granulated to prepare 28% thiacloprid·butene fipronil water dispersible granules. After testing, the active ingredient content is 28%, the suspension rate is ≥75%, the water content is ≤2.5%, the pH is 7.1, the particle size range (225-800um) is ≥98%, the dispersibility is ≥85%, the wetting time is ≤90s, and the wet sieve test ( Through 75μm sieve) ≥ 98, long-lasting foaming (after 1min) ≤ 12ml, qualified for accelerated thermal storage stability.

Abstract

The invention relates to an insecticide composite with thiacloprid and butylene fipronil, belonging to the field of desinsection, and the composite is combined by the thiacloprid and the butylene fipronil. The insecticide composite has obvious synergistic effect, and is mainly used for controlling rice fulgorids, vegetable thrips and other piercing and sucking type pests.

Description

Technical field: [0001] The invention belongs to the technical field of pesticides, and in particular relates to an insecticidal composition composed of thiacloprid and butene fipronil. technical background: [0002] The chloronicotinoid or neonicotinoid insecticide imidacloprid has been one of the most effective pesticide active ingredients used in agriculture in the past decade to control sucking and some chewing mouthparts pests. Therefore, Bayer Agrochemical Company of Germany and Bayer Agrochemical Company of Japan have carried out extensive research and development cooperation, and Bayer Agrochemical Company of the United States has discovered another insecticide thiacloprid with this type of structure. Thiacloprid is a new broad-spectrum insecticide with high efficiency on piercing-sucking mouthparts. According to different crops, pests and application methods, the dosage is 48-180g a.i. / hm 2 . Field trials have shown that thiacloprid has excellent control effects o...
