Embodiment 1

[0023] The original drug (in this application document, the original drug refers to butene fipronil and pyridaben, which will not be described in detail below), various auxiliary agents and fillers are fully mixed, pulverized by an ultrafine pulverizer, and formulated into a wettable powder. For example the following formula:

[0024] Butylene Fipronil 20%

[0025] Pyridaben 1%

[0026] Sodium lauryl sulfate (surfactant) 2%

[0027] White carbon black (filler) 5%

[0028] Vinylpyrrolidone (binder) 3%

[0029] Sodium lignosulfonate (dispersant) 6%

[0030] Attapulgite (filler) makes up to 100%.

Embodiment 2

[0032] Except prescription, the preparation method of present embodiment and embodiment 1 is basically the same. The formula is as follows:

[0033] Butylene Fipronil 2%

[0034] Pyridaben 68%

[0035] Chaku powder (surfactant) 5%

[0036] Polyvinyl alcohol (dispersion binder) 8%

[0037] Sodium lignosulfonate (dispersant) 9%

[0038] Bentonite (filler) make up to 100%

Embodiment 3

[0040] Add the solvent, the original drug, and the emulsifier respectively, mix well, and if necessary, heat and dissolve in a hot water bath to obtain transparent butene fipronil·pyridaben emulsifiable concentrate. For example the following formula:

[0041] Butylene Fipronil 1%

[0042] Pyridaben 15%

[0043] Nongru No. 500 (emulsifier) ​​8%

[0044] Nongru No. 700 (emulsifier) ​​3%

[0045] Ethanol (solvent) 8%

[0046] Xylene (solvent) make up to 100%

Abstract

The invention provides a pesticide composition and application thereof. Active constituents in the composition are butene-fipronil and pyridaben; and the composition is suitable to control pests and pest mites in agriculture. The pesticide composition has the following advantages: (1) the composition shows excellent synergy effect within certain range of mixture ratio, the insecticidal effect of the composition is obviously improved than single pesticides, using dosage of pesticides as well as pesticide application labor and cost are reduced at the same time, and the adverse effect on the environment and the pesticide residue are also reduced; (2) the two effective constituents in the composition have different action mechanisms, and the application of the composition can prolong or overcome the drug fastness of the pests, and prolong the service life of the single pesticides; and (3) the composition can control the pests and can control pest mites synchronously.

Description

technical field [0001] The invention relates to a pesticide composition, which is used for preventing and controlling agricultural pests and harmful mites. Background technique [0002] Rice planthopper is an important pest in rice production in my country. The harm of rice planthopper to rice mainly has three aspects: 1. Piercing and sucking rice juice. Adults and nymphs of rice planthoppers cluster in the lower part of the rice bushes, use their piercing and sucking mouthparts to penetrate into the rice stem tissue to suck juice, and when eating, the salivary glands secrete a toxic substance, which destroys the rice plant tissue and appears on the damaged stem. Many brown spots, when the damage is serious, the base of the grass is dark brown, and the whole plant gradually dies. When the number of insects is large, it often causes the rice to wither and die in a short period of time, and the rice fields become flat with dead stems. When a large number of damages occur in...
