Effect test

Embodiment 1

[0017] Weigh 959.5 g of biscuits and pulverize them into biscuit powder (average particle diameter about 150 μm) with a pulverizer. Weigh 0.5g of fipronil technical material and 10g of potassium sorbate, blend with a small portion of biscuit powder evenly, and then fully stir with most of the biscuit powder. Weigh 30g of commercially available fumed silica (particle size 7-40nm), add it to the mixed toxic biscuit powder, and then stir well to obtain an enhanced red fire ant killer. The comparative test of the killing effect of the RIFA has confirmed that this enhanced RIFA killing agent has a good killing effect on the RIFA.

Embodiment 2

[0019] Weigh 998.99 g of biscuits and grind them into biscuit powder (average particle diameter about 150 μm) with a pulverizer. Weigh 0.01g of the original drug of avermectin, first blend evenly with a small part of biscuit powder, and then fully stir with most of the biscuit powder. Weigh 1g of diatomaceous earth (particle size 7-40nm), add it to the mixed poisonous cake in the powder, and then stir well to obtain the enhanced red imported fire ant killer. The comparative test of killing effect has confirmed that this enhanced RIFA killer has a good killing effect on RIFA.

Embodiment 3

[0021] Weigh 880 g of biscuits and pulverize them into biscuit powder (average particle diameter about 150 μm) with a pulverizer. Weigh 10g of the mixture of spinosad original drug and hydrazone original drug, and 10g of potassium sorbate, blend evenly with a small portion of biscuit powder, and then fully stir with most of the biscuit powder. Weigh 100g of a mixture of tricalcium phosphate and zeolite powder (particle size 7-40nm), add it to the mixed poisonous cake in the powder, and then stir well to obtain an enhanced red fire ant killer. The comparative test of the killing effect of the ant killer has confirmed that this enhanced red fire ant killer has a good killing effect on the red fire ant.

Abstract

An intensified insecticide for red ant is proportionally composed of the mixture of fipronil, abamectin, hydramethylnon, pyripropanol, etc, the cracker powder, the nanoparticles of one or more of SiO2, diatomite, tricalcium phosphate, zeolite, TiO2, alumina, etc, and potassium sorbate.

Description

technical field [0001] The invention relates to an insecticide, in particular to an enhanced red fire ant killer. Background technique [0002] The red fire ant (Solenopsis invicta Buren) is an invasive and dangerous pest that invades farmland and houses and causes harm to humans and animals. It has strong reproductive ability and rapid spread, making it difficult to control. [0003] At present, the "two-stage method" is most widely used in the world to prevent and control RIFA, that is, in the first stage, poisonous baits are spread mechanically in a large area to trap and kill them, and in the second stage, contact pesticides are used to kill independent ant mound nests. Although the effect is good, the workload is very heavy, especially the cost and workload of filling nests far away from the water source is very high, and the poisonous bait spread is greatly affected by the weather. [0004] Most of the areas in my country that have been invaded by RIFA are the souther...
