Abstract
The invention discloses an azocyclotin acaricide, belonging to acaricide technology of plant protecting field. The invention composition comprises fenbutatin oxide 10-800 parts, moistening agent 10-40 parts, dispersing agent 20-40 parts, disintegrating agent 10-50 parts, sorbent 10-60 parts, adhesive agent 10-30 parts, stabilizing agent 10-70 parts and filling material 50-500 parts. The above components are pro rata mixed and evenly stirred, then mesh powder obtained through disintegrating is evenly stirred with the adhesive agent, and azocyclotin moisture free-flow agent is processed through granulating, drying and sieving. The azocyclotin acaricide of the invention overcomes shortages of the conventional agent type of azocyclotin, lowers utilizing cost for farmers and environmental pollution. During utilizing process, the chemical compound fenbutatin oxide moisture free-flow agent of the invention has the advantages of high content, fast disintegration, great dispersibility, favorable storing and transporting, great stability, high activity, great efficiency and safety, which is mainly applicable for preventing and curing European red mites and citrus red mites.
Description
Technical field
The present invention relates to a kind of farm killing mite agent, active ingredient is azacyclotin, and formulation is water dispersible granules and preparation method thereof.
Be mainly used in the control of European red mite, citrus red mite.
Background technology
At present, the farm killing mite agent is a lot, and azacyclotin is wherein a kind of, belongs to the organic tin miticide, is the stronger broad spectrum activity miticide of action of contace poison.Can kill if mite, one-tenth mite and summer egg are invalid to winter egg.Light and rainwater are had stability preferably, and the longevity of residure is longer.Under typical concentrations to crop safety.The agent of the former powder list of azacyclotin in the market, the wetting powder that has been made generally in low content uses and the use of low content missible oil.And the agent of wettable powder list and missible oil are seriously polluted in preparation and use, and human and environment is all had very big harm, and effective rate of utilization is low, lasting period is short, and be that agricultural chemicals development intermediate frequency faces superseded formulation, the fortune storage is inconvenient, is difficult for shortcomings such as packing, use cost height.Water dispersible granules not instrument has 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.
European red mite: the main harm blade, the canescence spot appears in the blade initial stage of being injured, and blade cloth presents grey canescence when serious, but do not fall leaves, mainly influenced the photosynthesis of crop, not only cause blade withered and yellow, also cause tree vigo(u)r to wilt, cause for the whole physiology phase and have a strong impact on.
Citrus red mite: the oranges and tangerines producing region spreads all over the country, it is worldwide oranges and tangerines evil mite, it is the main harmful mite in China oranges and tangerines producing region, oranges and tangerines nursery stock, treelet and big tree all are injured, and it is the heaviest to be injured with nursery stock and treelet, mainly stings the juice of phyllidium sheet, spray and fruit etc., be injured the heaviest with blade, cause harm and cause leaf abscission and spike top when serious, often cause a large amount of sheddings, have a strong impact on output and tree vigo(u)r.
Summary of the invention
The objective of the invention is to improve one satisfactory for result, the efficient height, active ingredient usage amount height, environmental pollution is little, use easily, use cost is low, and the safety coefficient height is pollution-free to the crop blade face, can promote the photosynthesis of crop, packing is simple, and 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 like this realize that its compound of a kind of azocyclotin water dispersible granule comprises: 50 parts～500 parts of fenbutatin oxide 10-800 parts, wetting agent 10-40 part, dispersant 20-40 part, disintegrant 10-50 part, adsorbent 10-60 part, adhesive agent 10-30 part, stabilizing agent 10-70 part, filler.Wherein, the auxiliary agent type that water dispersible granules according to claim 1 is required is prepared 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.
The preparation method's of a kind of azocyclotin water dispersible granule of the present invention technology, the technical indicator of product is as follows:
Azacyclotin content 1-80%
