Abstract
The invention relates to a powdery seed coating agent for the prevention and cure of underground pests of sprout period corns and soybeans containing chlorpyrifos, wherein the agent comprises 1-50 wt% of chlorpyrifos, 1-50 wt% of bactericidal agent, 1-20% of surface active agent, 1-20% of binding agent and film former, 0.1-2% of aposematic coloration and right amount of extender.
Description
Technical field
The present invention relates to chlopyrifos and be the powder kind clothing agent that is used for control of maize, soybean seedling soil insect of active ingredient.The organophosphorous pesticide active ingredient of saying so in more detail chlopyrifos cooperates through bactericide, surfactant, binding agent and the film forming agent of screening, warning colouration and an amount of filler, the powder kind clothing agent formulation with better Environmental compatibility that processes from strand.
Background technology
The seed chemicals treatment is one of method of economical and convenient in the crop pest control, also is the efficient precisely important measures of dispenser.For a long time, the method for seed treatment be basically use that pulvis, wetting powder, aqua, missible oil etc. are dressed seed, seed soaking or vexed kind, the water-based property suspending agent that can flow carries out dressing to seed.Pulvis, wetting powder seed dressing, medicament comes off easily to the poor adherence of seed, and the drug effect phase is short, does not also contain warning colouration, and heavy contamination is absolutely unsafe to people and animals simultaneously, now progressively eliminates; Soup seed soaking, vexed kind, because of required medicament or soup are had particular requirement, the seed of handling needs instant sowing, has limited the application of this measure to a certain extent.And the seed pelleting medication is hiddenly concentrated, target has reduced pesticide hazards by force, to greatest extent, has realized economic, society, ecological benefits simultaneous growth, is to improve the breeding quality, realizes the important measures of seed standardization, commercialization and industrialization.In recent years, existing many patents about the agent of agricultural chemicals kind clothing, but these patents only limit to the research of water base property suspending agent kind clothing agent, for example CN1228256A mostly; And for the research of powder kind clothing agent, concrete disclosed among the CN99123069.8 1296750A is Isofenphos methyl, thimet or parathion-methyl.All there is defective to some extent in above prior art, shows that mainly 1. water base property suspending agent kind clothing agent exists volume, freight volume and Packing Unit big in producing, and the preparation stored poor stability uses problems such as poisoning risk height.2. Isofenphos methyl, thimet or parathion-methyl belong to high, highly toxic pesticide, are used for the easy contaminated environment of seed pelleting and cause the person poultry poisoning.
Summary of the invention
The objective of the invention is to release a kind of production, storing safety, use laborsavingly, and have the powder kind clothing agent formulation of better Environmental compatibility.Replace the conventional water base property suspension seed-coating agent that uses from formulation, replace present widely used furans pellet, contour, the highly toxic pesticide of thimet from active ingredient, improve the quality of the pharmaceutical preparations, reduce environmental pollution and person poultry poisoning, realize the sustainable development of the formulations of pesticide.
To achieve these objectives, the present invention is 1. according to corn, common soil insect harm in the seedling stage present situation of soybean, select the pesticide active ingredient of chlopyrifos as the control soil insect, substitute present widely used furans pellet, contour, the highly toxic pesticide of thimet, greatly reduce preparation toxicity, improved safety in utilization.Chlopyrifos is efficient, poisoning, broad-spectrum organophosphorous pesticide, can by tag, stomach toxicity, stifling mode prevent and treat soil insect, to crop safety, be widely used in the control of soil insect both at home and abroad, also there is not research report at present about the powder kind clothing agent that contains chlopyrifos.2. according to corn, the common sprout term disease of soybean, select suitable compatibility bactericide, realize and the synergy of chlopyrifos and the safety of assurance seed.3. according to the current situation of present seed coating technology, select the agent of powder kind clothing as the preparation processing formulation, the pesticide active ingredient storage that has effectively overcome the water base property suspension seed-coating agent existence of conventional use is decomposed and problems such as preparation stored layering, caking.
The technical solution used in the present invention is: a kind of powder kind clothing agent that contains chlopyrifos that is used for control of maize, soybean seedling soil insect, wherein contain chlopyrifos, bactericide, surfactant, binding agent and film forming agent, warning colouration and an amount of filler, it is characterized in that: 1. weight percentage is 1～50% chlopyrifos; 2. bactericide is some or a mixture that certain is several in carbendazim, tmtd, hydroxyisoxazole, the carboxin, and weight percentage is 1～50%; 3. surfactant is some or a mixture that certain is several in sldium lauryl sulfate, nekal (drawing back powder), lauryl alcohol polyethylene glycol oxide base ether, the naphthalenesulfonic acid-formaldehyde condensate (NNO), and weight percentage is 1～20%; 4. binding agent and film forming agent are some or mixtures that certain is several in xanthan gum, polyvinyl alcohol, polyethylene glycol, poly amic acid, polyvinylpyrrolidone, the Magnesiumaluminumsilicate, and weight percentage is 1～20%; 5. warning colouration is some or two a mixture in acid scarlet, the acid fuchsin, and weight percentage is 0.1～2%; Surplus is an amount of filler, is some or mixture that certain is several in bentonite, talcum powder, the white carbon.
Wherein, powder kind clothing of the present invention agent, single preferable range with fungicide carbendazim, tmtd, carboxin weight percentage is 10～25%; The preferable range of used fungicide carbendazim and 1: 1.5 mixture of tmtd weight percentage, carboxin and 1: 2 mixture of tmtd weight percentage, hydroxyisoxazole and 1: 15 mixture of carbendazim weight percentage is 10～30%.
The preparation method of powder kind clothing of the present invention agent is, at first the former medicine of chlopyrifos, bactericide original drug, surfactant, binding agent and film forming agent, warning colouration and an amount of filler are accurately taken by weighing by formula rate, fully mix in the adding blender, be crushed to the regulation fineness with airslide disintegrating mill then.
Used bactericide was some or a mixture that certain is several in carbendazim, tmtd, hydroxyisoxazole, the carboxin when the present invention made; Used surfactant is some or a mixture that certain is several in sldium lauryl sulfate, nekal (drawing back powder), lauryl alcohol polyethylene glycol oxide base ether, the naphthalenesulfonic acid-formaldehyde condensate (NNO); Used binding agent and film forming agent are some or mixtures that certain is several in xanthan gum, polyvinyl alcohol, polyethylene glycol, poly amic acid, polyvinylpyrrolidone, the Magnesiumaluminumsilicate; Used warning colouration can be some or two a mixture in acid scarlet, the acid fuchsin; Used filler is some or a mixture that certain is several in bentonite, talcum powder, the white carbon.
