Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of preparation method and application thereof of sustained-release granular formulation.
Background technology
Nearly ten years, along with the adjustment of agricultural planting structure, Protectorate cultivation has had in China and has developed by leaps and bounds.Whole nation protecting field area is more than 2,000,000 hectares.Along with the continuation development of protecting field and the cultivation year after year of high added value crop, the problem of soil-borne disease will be more and more outstanding, and will become the key factor of serious restriction protecting field development.According to inventor in Shandong, Hebei, Jiangsu, Liaoning, Zhejiang, the investigation of the ground such as Henan, the harm of soil-borne disease has become the outstanding problem in Protectorate cultivation.For the ginger cultivation district in Anqiu, Shandong, the soil-borne diseases such as curing ginger stalk rot, ginger bark favus occur very serious.In the face of serious soil-borne disease, peasant adopts Celfume to fumigate soil usually, Be very effective, but eliminating along with Celfume, the fumigant such as chloropicrin, dazomet becomes the leading role of soil-fumigating gradually.But because the cost of soil-fumigating is very high, general all at about 2000 yuan/mu, for the plot that soil-borne disease morbidity is relatively light, conventional bactericide and nematocide can be adopted to prevent and treat, but in the market, extremely lack the agriculture chemical compounding medicament having sterilization concurrently and kill line activity.Generally need the medication respectively of bactericide and nematocide, complex operation, time-consuming, take a lot of work, if by bactericide and nematocide efficient combination, can recruitment be greatly reduced, save time, laborsaving.Meanwhile, by the compound drug of metalaxyl and Avermectin, being processed into the granule with slow-release function by adding zeolite powder, can dispenser being facilitated on the one hand, and saving of labor, to save time; Active ingredient metalaxyl and Avermectin slow releasing can be made on the other hand, increase the lasting period of agricultural chemicals, reduce agricultural chemicals number of times, improve the availability of agricultural chemicals; Meanwhile, the peculiar flourishing hole of zeolite powder can be made full use of, excellent absorption property, thus effectively remove soil ammonium-state, simultaneously fertilizer conservation, water conservation, significantly improve crop growing state, increase crop yield.At present, the granule that there is not yet metalaxyl and the Avermectin with slow-release function carries out registering or bibliographical information.
Metalaxyl, English name metalaxyl, the main synthesis suppressing germ mycelium internal protein, makes its nutritional deficiency, can not normal growth and dead.Belonging to low-toxin farm chemicals, is internal absorption characteristic bactericide, has protection and therapeutic action, has Bidirectional Conduction performance, can be absorbed, and run to all parts of a plant with moisture content in plant corpus by the root of plant, stem, leaf.Application process is seed treatment and soil and cauline leaf spraying, for soil disinfection, controls soil-borne disease etc.
Avermectin, English name Avermectins, be that the class first developed by Japanese North university large village intelligence etc. and Merck company of the U.S. has desinsection, kills mite, ten hexa-atomic Macrocyclic lactone compounds of eelworm-killing activity, fermented by streptomyces griseus Streptomyces avermitilis in streptomycete and produce.Have insects and mites and tag and stomach poison function have faint fumigation action, without systemic action.But it has very strong osmosis to blade, subepidermal insect can be killed, and the longevity of residure is long.It is ovicidal not.Its mechanism of action and general insecticide disturb neurophysiology movable unlike it, stimulate release r-aminobutyric acid, and r-aminobutyric acid has inhibitory action to arthropodan nerve conduction, if namely there is paralysis symptom after becoming mite to contact with medicament with larva with insect in mite class, inertia does not take food, dead after 2 ~ 4 days.Because not causing insect rapid dehydration, so its lethal effect is slower.Though have direct killing effect to predatism and parasite, because plant surface is residual few, therefore little to the damage of beneficial insect.Simultaneously obvious to the root-knot nematode effect in soil.
Natural zeolite is also called zeolite, is the aluminium silicate mineral of a kind of rack-like structure that slag is formed, and has excellent absorption, ion-exchange performance.To be that natural Zeolite Rock is levigate form zeolite powder, and color is white.Zeolite possesses the various primary conditions of carrier and the thinner making additive pre-composition, zeolite be neutral pH between 7 ~ 7.5, when it is moisture only 3.4 ~ 3.9%, and not moisture-sensitive.The coarse loose structure with having of zeolite surface, make it have stronger carrying capability, material not only can be made to be adsorbed on surface equably, and can be adsorbed onto in hole and passage, the utilizability that improve material also improves the uniformity of mixing greatly.More be conducive to plant absorption the release time of energy proper extension medicine simultaneously.In addition, zeolite can be processed on request, generally can select arbitrarily between 200 orders at 30 orders.This specification for different material selection carrier and thinner provides great convenience.Zeolite is acidproof, and unit weight is 1.2 ~ 1.4kg/ liter, containing grease and raw fiber again without electrostatic phenomenon, these characteristics all meet the condition that carrier and thinner should possess.
Simultaneously, it is micro-with ultramicro-element and organic active substance that zeolite powder contains the organic and mineralising of abundant nitrogen, phosphorus, potassium, by release, conversion, exchange, substitute activity enzyme, directly provide comprehensively directly and indirectly nutrient to crops, Plants and Soils, water conservation, fertilizer-preserving ability can be improved.
Therefore, using the slow-released carrier of zeolite powder as metalaxyl and Avermectin, both the slow releasing of metalaxyl and Avermectin can have been met, the effect of zeolite powder improvement soil can be given full play to simultaneously, improve the ability of soil water-retaining, fertilizer conservation, can crop growing state be significantly improved, increase crop yield, thus reach the effect of killing two birds with one stone.
