Abstract

The invention relates to an agricultural pesticide, which utilizes dimilin as an effective component, and a water dispersed granulars agent prepared from the pesticide can be used for preventing cabbage worms of brassicaceous vegetable. The components of the pesticide comprises the dimilin, aids and stuffing; the aids are a dispersant, a wetting agent, a disintegrating agent and an adhesive; the stuffing is one or more than two mixing stuffing of white carbon, argil, bentonite, light calcium carbonate, attapulgite earth, talcum powder and kaolin,. The invention can be used for solving the problem of a missible oil microbial inoculum of low glitter, low storage and transport safety, poor worm killing effect, high cost and environment pollution. The invention can be quickly disintegrated and dispersed, and has a stable dispersion system; the preparations does not result in dust flying during the production, using and packing processes, thus being safe to the operator and free of environmental pollution; compared with the wettable powder, the invention has the advantages of large density, small size, greatly reduced packing and storage and transport expenses, convenient recovery of the packing materials, and prevention effect as high as 85.76 to 98.56 percent, which is 1.5 times than that of the prior art.

Description

A kind of Chlorbenzuron water-dispersing granules preparation

Technical field

The present invention relates to a kind of agricultural insecticide, is to be active ingredient with the young urea that goes out, and the water dispersible granules of making is prevented and treated the cabbage caterpillar of the brassicaceous vegetable on the agricultural.

Background technology

The young urea that goes out has another name called mieyotmiao No.3, suniao No.1, and monochloro-benzene is grand, English name: chlorbenzuron

Structural formula:

Molecular formula: C ₁₄H ₁₀N ₂O ₂Cl ₂

Adjacent chlorobenzene formacyl-3-(4-chlorphenyl) urea of chemical name: 1-

The young urea that goes out is the insecticide of benzoyl base class, and its effect characteristics and diflubenzuron are together.This agent mainly is stomach poison function, tags next, and the longevity of residure reaches 15-20 days, resistance of rainwater washing against, and degradation speed is slow in the field, to useful animals safety.Be fit to integrated control.

Cabbage caterpillar is a modal insect on the brassicaceous vegetable, and its adult white butterfly of choosing dishes from a menu mainly contains 5 kinds, i.e. imported cabbageworm, spot white butterfly, large white butterfly, east white butterfly, brown arteries and veins white butterfly at home.Wherein, imported cabbageworm is that China's distribution is the widest, one of the most serious insect pest of causing harm.The larva of imported cabbageworm cries cabbage caterpillar.Known host plant has 35 kinds, but the brassicaceous vegetable of mainly causing harm.As Chinese cabbage, cauliflower, rape etc.Cabbage caterpillar just gnaws mesophyll at blade back the length of time, and residual epidermis is little shape pit, eats leaf after 3 ages and becomes hole or incise.When serious, only residual vein and petiole.Discharge a large amount of ight soil simultaneously, pollute dish leaf and cabbage heart, make quality of vegetable become bad, and insect bite causes dish strain generation soft rot again for Bacteria erwinia provides the invasion approach, the death of acceleration complete stool.

The prevention and control office of meeting an urgent need of the Ministry of Agriculture attaches great importance at this insect, and strengthens the guidance to extermination of disease and insect pest work.At this situation, we have released the very high Chlorbenzuron water-dispersing granules preparation of active component, and it is all to have high susceptibility at insect such as the cabbage caterpillar of brassicaceous vegetable and oneself produces resistance to organic phosphor, carbamate and pyrethroid insectide insect.

In addition, agricultural insecticide is a lot, and the young urea that goes out is wherein a kind of.It has the insecticidal activity height, and security performance is good, the characteristics that fungicidal spectrum is wide.But benzoylphenyl urea original medicine is made generally in wetting powder in using at present and suspending agent uses.Because wetting powder dust pollution in processing and use is serious, and environment and people's health is had very big harm, and shortcomings such as effective rate of utilization is low, lasting effect is short, therefore be to fall behind relatively in the present formulations of pesticide and frequency faces superseded formulation; Though suspending agent is the environmental protection formulation, aborning to the technological requirement height, can not realize at present the preparation of high-load, and its lifes, packing, cost of transportation is also high, thereby causes the defective of the increase of production and use cost.

Summary of the invention

It is low to the purpose of this invention is to provide a kind of reduction environmentally safe and use cost, the availability height, and the young urea that goes out that activity is very high is prepared into a kind of Chlorbenzuron water-dispersing granules preparation.

In order to overcome environmental pollution that prior art exists, to be detrimental to health and shortcoming such as use cost height, technical scheme of the present invention is to solve like this:

A kind of Chlorbenzuron water-dispersing granules preparation, its special adaptations part are to include 3 parts～90 parts young ureas that go out by portion rate, 0.5 part～50 parts auxiliary agents, and 5 parts～48 parts fillers, described auxiliary agent is meant dispersant, wetting agent, disintegrant, stabilizing agent, binding agent; Described filler be white carbon, potter's clay, bentonite, precipitated calcium carbonate, attapulgite, talcum powder, kaolin, in one or more mixed fillers.Include 10 parts～50 parts young ureas that go out by portion rate, 3 parts～40 parts auxiliary agents, 10 parts～40 parts fillers.

Include 15 parts～45 parts young ureas that go out by portion rate, 5 parts～35 parts auxiliary agents, 15 parts～35 parts fillers.

Include 20 parts～40.5 parts young ureas that go out by portion rate, 10 parts～30 parts auxiliary agents, 18 parts～30 parts fillers.

Include 25 parts～38 parts young ureas that go out by portion rate, 12 parts～29.5 parts auxiliary agents, 20 parts～25 parts fillers.

Described dispersant is one or more mixed dispersants among sodium phosphate trimer, sodium lignin sulfonate, NNO, calcium lignosulfonate, polyoxyethylene oxypropylene ether, diffusion agent N O, the diffusant FO.

Described wetting agent is that tea is withered, Chinese honey locust, sldium lauryl sulfate, ethoxylated dodecyl alcohol sodium sulphate, neopelex, draw back in powder, penetrant t, penetrating agent JFC, the Tween 80 one or more and mix wetting agents.

Described stabilizing agent is one or more mixed stabilizers among tributyl phosphate, triphenyl phosphite, the BHT.

Described disintegrant is one or more mixing disintegrants in ammonium sulfate, calcium chloride, magnesium chloride, aluminium chloride, bentonite, the urea.

Described binding agent is one or more hybrid adhesives in starch, dextrin, gum Arabic, soybean protein, gelatine, sodium sulphate, gypsum, polyvinyl alcohol, rosin, paraffin, carboxymethyl cellulose, the sodium silicate.

Described filler is one or more the mixed fillers in white carbon, potter's clay, bentonite, precipitated calcium carbonate, attapulgite, talcum powder, the kaolin.

Above auxiliary agent all is known substances, also is the common and material known in the pesticidal preparations processing.

The present invention compared with prior art, a kind of Chlorbenzuron water-dispersing granules preparation, it is exactly to be mixed together the granule that obtains of processing with the young urea that goes out with auxiliary agent and filler, can disintegration rapidly, dispersion in water, form higher suspension and stable dispersion.It belongs to the bactericide that plant protection is used, and is used to solve the missible oil microbial inoculum and has that flash of light is low, unsafe storage, insecticidal effect are poor, the problem of cost height and environmental pollution.And this preparation no dust drift in production, use, packaging process, to operator's safety, nonpollution environment, compare with wetting powder, density is big, volume is little, can reduce packing, storage fee usefulness significantly, and packing material is also convenient to be reclaimed, control efficiency is 85.76%～98.56%, is more than 1.5 times of prior art.
