During utilizing process, the diafenthiuron insecticide and acaricide of the invention have the advantages of high content, fast disintegration, great dispersibility, favorable storing, great stability, high activity, great efficiency and safety, which are mainly applicable for preventing European red mites, citrus red mites, tea leafhoppers, cotton bollworms, vegetable diamondback moths and vegetable cabbage caterpillars.
Description
Technical field
The present invention relates to a kind of agricultural insecticidal miticide, active ingredient is the butyl ether urea, and formulation is water dispersible granules and preparation method thereof.Be mainly used in the control of European red mite, citrus red mite, tealeaves tea lesser leafhopper, cotton cotton bollworm, vegetables diamond-back moth, vegetables cabbage caterpillar.
Background technology
At present, agricultural insecticidal miticide kind is a lot, the agent of butyl ether urea list is unique highly active insecticidal/acaricidal agent that has market most, inhale and fumigation action in having, to becoming mite, young mite, all having efficiently as if mite, can also be used for simultaneously insect and evil mites such as leafhopper, aleyrodid, aphid, two spotted spider mite, cotton bollworm, diamond-back moth and cabbage caterpillar on tealeaves, cotton and the vegetables, remarkably productive.Butyl ether urea raw powder list agent 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is low, lasting period is short, and be that agricultural chemicals development intermediate frequency faces superseded formulation, the fortune storage is inconvenient, is difficult for shortcomings such as packing, use cost height.Water dispersible granules has not only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.
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.
The tealeaves 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.
Cotton bollworm: claim boll fruit armyworm again, can endanger solanberry class, cotton, corn etc., larva is got leaf that food do not launch earlier, and to make leaf launch the back broken, and moth food in moth flower bud, flower, the fruit is bored in the back, cause bud drop, fallen flowers and fruit to be eaten hole or eat the sky fruit, influence output and the quality of cotton.
Vegetables diamond-back moth: belong to Lepidoptera, diamond-back moth section.Be commonly called as hang spring worm, diamond-back moth.Be a kind of global vegetable-crop pest-insect, the whole nation generally takes place.Mainly posting plant is brassicaceous vegetable, and it is the heaviest wherein to be injured with wild cabbage, cauliflower, Chinese cabbage, rape etc. again, mainly based on larva harm blade.Young larva can pierce in the mesophyll causes harm, and slightly greatly promptly gnaws leaf surface and mesophyll, and residual one deck epidermis forms irregular speculum.3～4 instar larvaes can be eaten into blade hole and incising, and when serious blade are eaten to reticulate.Concentrate the harm lobus cardiacus in Chinese cabbage seedling stage, make the plant can not normal growth.
The vegetables cabbage caterpillar: the important pests on the vegetables, it is very general to distribute.Brassicaceous vegetables such as main harm wild cabbage, cauliflower, Chinese cabbage, radish, rape are had a liking for wild cabbage and cauliflower especially partially.Gnaw the vegetables blade with larva, can only gnaw mesophyll before 2 ages, stay the epidermis of layer of transparent; Can nibble whole blade after 3 ages, gently then be and incise shape, heavy then only surplus vein influences the vine growth and development and the bag heart, cause the underproduction.The worm excrement pollutes the cauliflower bulb, reduces commodity value.When causing harm Chinese cabbage, can cause the generation of soft rot.
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 a kind of fenbutatin oxide water dispersible granule composition comprises: 50 parts～500 parts of butyl ether urea 20-800 parts, wetting agent 20-40 part, dispersant 20-40 part, disintegrant 20-80 part, adsorbent 10-60 part, adhesive agent 10-50 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.
