Abstract
The invention discloses a formula and a preparation method of a granular pesticide. The granular pesticide comprises the following components in parts by mass: 3-5 parts of hoxim, 1-20 parts of adsorbent, 0.1-2 parts of stabilizer, 0.1-2 parts of synergistic agent, 1-5 parts of dispersant, 1-10 parts of adhesive, 0.1-1 part of coloring agent and 55-90 parts of carrier. By adopting attapulgite as the pesticide carrier, the low-toxicity low-residue pesticide phoxim can be mixed with the adhesive and auxiliary agents in proportion to prepare granules, so that the invention not only overcomes the defects of short persistence of the conventional phoxim granules, but also has certain fertilizer efficiency, soil improvement and environmental protecting performance.
Description
Technical field
The present invention relates to prescription of a kind of granular agricultural chemical of preventing and treating the crops soil insect and preparation method thereof, particularly, relate to prescription of a kind of phoxim granule and preparation method thereof.
Background technology
Crops soil insect kind is very various, mainly contains cutworm, wireworm, grub, mole cricket, chafer etc., can endanger all kinds of crops substantially, and the harm loss is very serious.At present, the most frequently used method of preventing and treating is to spread fertilizer over the fields granule class agricultural chemicals in soil in the production.Common granular agricultural chemical has phoxim granule, thimet granule, chlopyrifos granule, Avermectin granule etc.Thimet granule toxicity height, residual heavy, incompatibility is promoted the use of, chlopyrifos granule, Avermectin granule cost height, lasting period weak point, large-scale popularization also has certain difficulty, though common phoxim granule price is moderate, but the lasting period is short, and is not ideal enough to the control effect of underground insect.
Summary of the invention
The objective of the invention is to, propose a kind of prescription of phoxim granule, with realize that target is strong, low cost of manufacture, medicament adsorption rate height, the advantage that the lasting period is long.
To achieve these goals, the technical solution used in the present invention is: at the problems referred to above, component of the present invention and quality proportioning are as follows:
Agricultural chemicals phoxim (active ingredient) in the above-mentioned prescription can be selected the cream preparation of former medicine or high-load for use.Stabilizing agent is selected one or more in organic phosphoric acid, phosphorous acid, hydroxyl sulfoacid, the triphenyl phosphate for use.Synergist is selected one or more in synergy phosphorus, methyl synergy phosphorus, organosilicon synergist, the Butacide for use.Dispersant is selected one or more in lignosulfonates (sodium or calcium salt), neopelex, spent pulping liquor, fatty alcohol-polyoxyethylene ether, the polyoxyethylene alkylphenol ether for use.Binding agent is selected one or more in bentonite, polyvinyl alcohol, polyvinylpyrrolidone, chitin, dextrin, the starch for use.Colouring agent (warning colouration) is selected acid scarlet, crystal violet, Acid Red B, magenta, product purple, a kind of in light green for use.Adsorbent can be selected one or more in white carbon, calcium carbonate, diatomite, talcum powder, the bentonite for use.Carrier adopts concavo-convex rod, and the concavo-convex rod carrier originates from Zhangye Linze county, Gansu Province.
Simultaneously, another technical scheme of the present invention's employing is:
A kind of preparation method of granular agricultural chemical comprises the steps: by the quality proportioning, after the adsorbent of 3～5 parts phoxims and 1～20 part is mixed, adds low amounts of water and makes little wet female powder; 55～90 parts carriers are screened into 20～40 purpose particles, after premixed in female powder of gained and the carrier input coating pelletizing machine, add 1～10 part binding agent, 0.1～2 part stabilizing agent, 0.1～2 part synergist, 0.1～1 part colouring agent and 1～5 part dispersant successively, fully mix the back discharging; Behind the gained dry materials, weigh packing.
The result shows through field experiment: before the crop-planting, this granule of weighing 45kg/ hectare, in company with broadcast application in soil, after 60 days, 90 days, 120 days, preventive effect to the carrot cutworm reaches 100%, 85.5%, 76%, is better than the preventive effect same period (preventive effect is respectively 75%, 45%, 32% after 60 days, 90 days, 120 days) of conventional phoxim granule.Simultaneously, granule of the present invention can significantly strengthen carrot field growing way, improves output (generally increase production 7%---13%).
The invention has the beneficial effects as follows:
This granular agricultural chemical, adopt concavo-convex rod as farm chemical carrier, low toxicity and low residue insecticide phoxim is mixed in proportion with binding agent, auxiliary agent, manufacture granule, not only overcome short drawback of common phoxim granule lasting period, also had certain fertilizer efficiency, soil melioration and the feature of environmental protection.The phoxim granular agricultural chemical that utilizes the present invention to prepare has that target is strong, low cost of manufacture, medicament adsorption rate height, long advantage of lasting period.
