Description
Technical field
The present invention relates to a kind of disinfectant use in agriculture, particularly a kind of water dispersion granules agent of dithane.
Background technology
At present, disinfectant use in agriculture is a lot, and zineb is wherein a kind of.Zineb (english common name: zineb, chemical molecular formula C
4H
6N
2S
4Zn) be the protectant that a kind of foliage spray is used, many germs such as Pseudoperonospora cubensis, late disease bacteria and anthrax bacteria etc. are had strong action of contace poison.To plant safety, the active ingredient chemical property is more active, in water, easily be oxidized to different thiocyanation compound, to the cause of disease thalline contain-enzyme of SH base has had strong inhibitory effects, and the direct kill pathogens spore of energy, suppress the germination of spore, stop in the germ invaded plants body, but very little to the mycelial lethal effect of cause of disease in the invaded plants body.Therefore, use zineb to prevent and treat disease and should grasp in the disease beginning and see that the phase carries out, just can obtain effect preferably.The drug effect phase of zineb is short, decomposes comparatively fast about 7 days of its longevity of residure at solar radiation and after absorbing airborne moisture.It has the bactericidal activity height, and security performance is good, the characteristics that fungicidal spectrum is wide.But the former powder of zineb is made generally in wetting powder and uses in using at present.Because wetting powder dust pollution in processing and use is serious, and environment and health are had very big harm, and shortcomings such as effective rate of utilization is low, lasting period weak point, therefore be the formulation that falls behind and be on the verge of to eliminate relatively in the present formulations of pesticide.
Summary of the invention
Purpose of the present invention is exactly in order to overcome the environmental pollution that exists in the prior art, to be detrimental to health and shortcoming such as use cost height and a kind of high-load of developing environment-friendly type, availability height, and water dispersion granules agent of dithane easy to use and component content thereof.Water dispersible granules is to grow up on the basis of wetting powder and suspending agent, this formulation has overcome the shortcoming of suspending agent and wetting powder, had both the low advantage of environmental protection and use cost, in processing and use, having reduced the pollution of environment and reduced peasant's use cost, is a main trend of present pesticidal preparations formulation development.
The objective of the invention is to realize by following technical scheme, the active ingredient of water dispersion granules agent of dithane is zineb, make rule or irregular particle by the former medicine of zineb and wetting agent, dispersant, disintegrant, thinner, binding agent hybrid process, the content of zineb is 40%～80% (percentage by weight).
Wherein: wetting agent can be a kind of of alkylnaphthalene sulfonate (BX), alkylsulfonate, sodium alkyl sulfate (K-12), sodium alkyl benzene sulfonate (ABS-Na), alkyl phosphoric acid sodium, alkylphenol-polyethenoxy base sodium sulphate; Dispersant can be a kind of of Fluhyzon formaldehyde condensation products (NNO), alkylphenol polyoxyethylene formaldehyde condensation products sodium sulphate, sodium lignin sulfonate, calcium lignosulfonate, polycarboxylate (2700); Disintegrant can be a kind of of Attapulgite, starch, sodium sulphate, ammonium sulfate, white carbon; Thinner can be a kind of of kaolin, precipitated calcium carbonate, diatomite; Binding agent can be a kind of of denaturated sodium polyacrylate 80, No. 72, polyethylene glycol, No. 3, modified polyvinyl alcohol, No. 54, lignin, carboxymethyl cellulose.
This formulation is easy to use except having, and cheap, drug effect is fast, to outside user and the Environmental security, also has following characteristics:
(1) disintegration rate of particle is fast;
(2) dispersed uniformly;
(3) there is not bulky grain after the dispersion, not blocking sprayer;
(4) good suspension stability;
(5) good fluidity;
(6) there is not dust;
(7) bin stability height;
(8) foam seldom;
(9) soup has good wetting property, permeability and plate-out ability;
(10) packing is suitable, need not the edge of a field metering;
(11) the papery packing be can use, recycling of packaging and secondary pollution avoided;
Owing to added the auxiliary agent of heterogeneity, make the present invention have the active component content height among the present invention, environmental pollution is little, and disintegration rate is fast, and dispersive property reaches heat storage steady performance well, bactericidal potency height in use, and safety is good.
