Description
Technical field
The present invention relates to a kind of agricultural insecticide, active ingredient is meta-tolyl-N-methylcarbamate (MTMC), and formulation is water dispersible granules and preparation method thereof.Be mainly used in the control of rice hoppers, rice leaf cicada, tea tree tea lesser leafhopper, tea tree Aleurocanthus spiniferus.
Background technology
Meta-tolyl-N-methylcarbamate (MTMC) is that insect has strong action of contace poison, and the power of knocking down is strong, and have certain fumigation action and in ooze effect, drug effect is rapid, and rice hoppers, rice leafhopper and tea tree tea lesser leafhopper, Aleurocanthus spiniferus are all had special efficacy.The preparation of meta-tolyl-N-methylcarbamate (MTMC) is mainly based on missible oil and wetting powder at present, content is mainly between 20-25%, and mainly there is following some problem in present preparation: (1) content is low, and dosage is big, does not reach ideal effect, efficient is low, (2) the active ingredient usage amount is low, and the filler usage amount is big, and is big for environment pollution, (3) use inconvenience, use cost height.(4) safety coefficient is low, and the crop leaf is had pollution, suppresses the photosynthesis of crop, and (5) packing is complicated, and storing is inconvenient, when use (6) human body is had certain injury.Water dispersible granules has not only reduced peasant's use cost, and has reduced the pollution to environment, and the present invention in use has content height, fast, the good dispersion of disintegration, is beneficial to the advantage of storing and stability, and activity is high, usefulness is good, safety.
Rice hoppers: rice fulgorid belongs to the Homoptera Delphacidae.Be the common disease of paddy rice, hazard rice mainly contain three kinds of brown planthopper, white-backed planthopper and small brown rice planthoppers.Endangering heavier is brown planthopper and white-backed planthopper, and the later stage is based on brown planthopper based on white-backed planthopper early stage for early rice; Middle late rice is based on brown planthopper.Small brown rice planthopper seldom directly causes disaster, but can propagate the virus disease of paddy and wheat, seeding corn and other crops.Adult of rice fulgorid and nymph are clustered in rice clump base portion thorn and inhale juice, make by the necrosis of harm browning, and nutrient and moisture loss cause yellow leaf, and it is short to grow, withered bar lodging when serious.Milk ripe stage, be injured, and makes spike of rice grouting discontented, forms blighted grain, and thousand kernel weight reduces, and has a strong impact on output.
The rice leaf cicada: it is with one-tenth, nymph, and it is main climbing to blade thorn absorption rice strain juice sooner or later.Evil portion becomes hickie, and nymph group evil forms foxiness.Cause the rice strain withered, the pool lodges.Have fulminant, the viral disease that also spreads disease, annual generation algebraically is more, and breeding amount is greatly the insect bigger to rice hazard.
The tea tree tea lesser leafhopper: belong to Homoptera, Cicadellidae, adult and nymph have obviously super tender property, dwell in tender leaf back side suction juice tea tree juice more, influence the normal conveying of tea tree nutriment, after tea tree was injured, its evolution was divided into dehydration phase, red arteries and veins phase, burnt limit phase, dried-up phase.The tea place that generally is injured, the summer autumn tea underproduction be more than 10%, heavyly then loses 30～50%.In addition, be subjected to the bud-leaf after false eye leafhopper endangers, broken in process, dust tea increases, and yield rate reduces, and easily produces the cigarette smell of burning, and tea leaf quality is also seriously influenced.
Tea tree Aleurocanthus spiniferus: belong to the Homoptera Aleyrodidae.Mainly draw tea tree juice with larva at blade back, the dew of divulging a secret side by side causes coal bacterium parasitism, brings out sooty mould, and tea tree is as dark as a stack of black cats when serious.The tea tree photosynthetic efficiency of being injured reduces, and germination density descends, and germinates late, and bud-leaf is thin and weak, and the tea tree fallen leaves are serious, not only influence tea yield and quality, and have a strong impact on the tea tree tree vigo(u)r.
Aleurocanthus spiniferus is inhaled tea tree with larva thorn and is become old leaf sap harm, takes place that tea shoot stops to sprout when serious, and tree vigo(u)r is weak, a large amount of fallen leaves, and its excreta also brings out sooty mould, causes fluffy a slice black of tea tree.
Summary of the invention
The objective of the invention is to improve a content height, dosage is little, and is satisfactory for result, the efficient height, active ingredient usage amount height, the filler usage amount is little, environmental pollution is little, uses easily, and use cost is low, the safety coefficient height, pollution-free to the crop blade face, can promote the photosynthesis of crop, packing is simple, storing is convenient, during use human body is not had the science environmental protection formulation of injury.Another purpose is to be prepared into outstanding formulation and easy to use, the high high-content water-dispersion granula of practical efficiency.
Technical scheme among the present invention and such realization, its composition of a kind of tebuconazole water dispersible granule comprises: meta-tolyl-N-methylcarbamate (MTMC) 10-800 part, wetting agent 10-50 part, dispersant 10-50 part, disintegrant 10-80 part, adsorbent 10-60, adhesive agent 10-50 part, stabilizing agent 10-60 part, filler 50-500 part.Wherein, the required auxiliary agent type of agent is found in aqueous dispersion according to claim 1, prepares according to the product concrete condition.
Owing to add the auxiliary agent of heterogeneity, make active quantities height of the present invention among the present invention, pollutes little, availability height, convenient, the stable easily use of storing.Have also that disintegration rate is fast, the advantage of good dispersion, good fluidity.
