Problems solved by technology

Individual chlorpyrifos and phoxim granules have a short duration of action due to improper carrier, and the effect is not ideal
At the same time, due to the lack of systemic properties, it has no effect on the pests lurking in the aboveground parts of plants.

Embodiment 1

[0023] Weigh 3.3 parts of chlorpyrifos technical material and 2.2 parts of imidacloprid into 10 parts of white carbon black, mix evenly, and set aside. Mix the above mother powder with 78.3 parts of sieved attapulgite (with a particle size of about 20-40 mesh) and add them to the coating granulator for stirring. While stirring, add 10% polyvinyl alcohol aqueous solution 3 1 part, 0.5 part of organic silicon synergist, 2 parts of calcium lignosulfonate, 0.5 part of triphenyl phosphate and 0.2 part of acid red B, mix well and discharge, then dry and sieve to get 100 parts of qualified products .

Embodiment 2

[0025] Weigh 5 parts of EC preparation with high content of chlorpyrifos and imidacloprid 2 original drug, add to 20 parts of calcium carbonate, mix evenly, set aside. Mix the above-mentioned mother powder with 53 parts of sieved attapulgite (with a particle size of about 20-40 mesh) and add them to the coating granulator for stirring. While stirring, add 10 parts of 10% starch aqueous solution, 2 parts of methyl synergist, 5 parts of fatty alcohol polyoxyethylene ether, 2 parts of phosphorous acid and 1 part of acid scarlet, mixed well and discharged, dried and sieved to obtain 100 parts of qualified products.

Embodiment 3

[0027] Weigh 3 parts of the original drug of chlorpyrifos and 2 parts of the original drug of imidacloprid into 4.7 parts of diatomaceous earth, mix evenly, and set aside. Mix the above-mentioned mother powder with 88 parts of sieved attapulgite (with a particle size of about 20-40 mesh) and add them to the coating granulator for stirring, and add 1 part of 10% dextrin solution gradually while stirring , 0.1 part of synergistic ether, 1 part of sodium dodecylbenzenesulfonate, 0.1 part of hydroxysulfonic acid and 0.1 part of pinnatine violet, mix well and discharge, dry and sieve to obtain 100 parts of qualified products.

Abstract

The invention discloses a granule pesticide formula and a preparation method thereof. The composition and mass ratio of the pesticide are as follows: 3-5 parts of chlorpyrifos, 2-3 parts of imidacloprid, 1-20 parts of adsorbent, and 0.1-2 parts of stabilizer , 0.1-2 parts of synergist, 1-5 parts of dispersant, 1-10 parts of binder, 0.1-1 part of colorant, 55-90 parts of carrier. The present invention uses attapulgite as a pesticide carrier, mixes low-toxicity and low-residue insecticides chlorpyrifos and imidacloprid with binders and auxiliaries in proportion to make granules, which overcomes the shortcoming of common underground pest granules with a short duration, And by adding the systemic insecticide imidacloprid, the insecticidal effect on above-ground pests is enhanced. At the same time, because the attapulgite is used as the carrier, the granules also have certain fertilizer efficiency, soil improvement and environmental protection.

Description

technical field [0001] The invention relates to a formula and a preparation method of a granule pesticide for controlling underground and above-ground pests of crops, in particular to a formula of chlorpyrifos and imidacloprid granules and a preparation method thereof. Background technique [0002] There are many kinds of pests above and below the ground of crops, mainly including cutworms, needleworms, grubs, mole crickets, scarabs, liriomyza, thrips, aphids, etc., which can basically harm all kinds of crops and cause serious damage. At present, the most commonly used control method in production is to spray granular pesticides into the soil to control underground pests, such as phoxim granules, phorate granules, chlorpyrifos granules, etc. Phorate granules are highly toxic and have Heavy, not suitable for promotional use. The single chlorpyrifos and phoxim granules have a short duration of action due to improper carrier, and the effect is not satisfactory. At the same ti...
