Abstract

Agriculture chemicals for prophylaxisthat that is a soluble powder prepared again from bactericidal agent and bluestone is made by mixing chalcanthite, anhydrous sodium carbonate and one of bactericial agents: C10H7CL2NO2 or C8CL1N2. The weight ratio is as following 68%-82% chalcanthite, 0.3%-1.2% one of bactericidal agents and remainder as anhydrous sodium carbonate, with water ration being 1:200-320. The invented agricultural chemicals provide merits of safety, high efficiency, lower cost, strong action to insects and mollusk etc.

Description

Disease-proofing pesticide--relative bactericide and cupric sulfate compounded soluble powder

The present invention relates to a kind of agricultural chemicals, specifically a kind of medicament for control crop fungi, bacterial disease.

According to interrelated data retrieval, at present also not with the present invention's identical medicament of filling a prescription.Prevent and treat the inorganic fungicide of crop pest in the past, mainly contained copper sulphate (CuSO ₄), bordeaux mixture (CuSO ₄XCu (OH) ₂YCa (OH) ₂ZH ₂O), cuprammonium mixture and tpn (C ₈Cl ₄N ₂), dimethachlon (C ₁₀H ₇Cl ₂NO ₂), carbendazim (C ₉H ₉N ₃O ₂) wait organic bactericide.But copper-bath has serious poisoning not use to most crops, and bordeaux mixture is with an amount of copper sulphate, quicklime (CuO), water (H ₂O), the cuprammonium mixture is that copper sulphate and ammonium-containing compound are formulated, and these two kinds of bactericide ginsengs are made into part and all need to buy respectively, are difficult for buying neat sometimes; Compound method is also more tired, is unfavorable for large scale application.As prepare bordeaux mixture and must earlier 90% water be allocated copper-bath, 10% water allotment milk of lime and perforated residue, then copper-bath is slowly poured in the milk of lime and the limit bevelling stirs, with the difference of crop species, kind, diseases prevention object, should use the bordeaux mixture of different multiple proportions; 1 kilogram in copper sulphate, 11 kilograms of ammonium carbonates are got in cuprammonium mixture preparation, grind respectively and fully are mixed, and sealing can be converted water and use after 24 hours in the slot watt cylinder of packing into immediately, mainly drenched soil control soil zone fungus diseases, the few application existing to the utmost to water; Though protection effect such as tpn, dimethachlon is better, price is expensive, and carbendazim was used through more than 20 years, and disease drug resistance significantly strengthens, and to the broad bean red spot, effects such as sclerotinia rot of colza significantly descend.

Purpose of the present invention, it is the weak point that overcomes above-mentioned bactericide, provide a kind of directly to water spray control crop fungi, bacterial disease, have safety, efficient, cheapness, drug effect length, stimulating growth, to various insects and snail deterrent effect by force, the wide spectrum disease-proofing pesticide--relative bactericide and the cupric sulfate compounded soluble powder of increase yield significantly.

The present invention is achieved by the following technical solutions, and the prescription of disease-proofing pesticide--relative bactericide and cupric sulfate compounded soluble powder is formed: by cupric sulfate pentahydrate (CuSO ₄5H ₂O), natrium carbonicum calcinatum (Na ₂CO ₃) and following bactericide: the dimethachlon (C of imines class ₁₀H ₇Cl ₂NO ₂), the tpn (C of aromatic hydrocarbons ₈Cl ₄N ₂) any one mixed composition in waiting, wherein cupric sulfate pentahydrate accounts for 68%-82% by weight, and any in the above-mentioned bactericide accounts for 0.3%-1.2%, and all the other be natrium carbonicum calcinatum, as adding micro-auxiliary agent zinc sulphate (ZnSO again ₄), barium chloride (BaCl ₂), can increase safety and adhesivity to crop, converting the water ratio during use is 1: 200-320.Take by weighing cupric sulfate pentahydrate in the production according to the above ratio and do dry the processing earlier, make it lose chemical combination attitude water 8%-12%, even mixed preparing quantitatively packs according to customer requirements again after mechanical ultramicro grinding; The present invention adds the solution of preparing after the suitable quantity of water, be the faintly acid colloidal suspensions, spray the back with microgranular crop surface and the germ rubbish face of adhering to, through the effect of factors such as air, moisture, carbonic acid gas and crop, germ secretion copper ion releasing gradually, and with the pathogen surface of cell membrane on the effect of SH enzyme, or be penetrated into that somatic cells is inner to be combined with some enzyme, influence its activity; Simultaneously can with cation exchange such as cell surface hydrogen, calcium, magnesium, potassium, its surface protein is solidified, help joining the infiltration of joining bactericide, further improve bactericidal activity, the performance synergistic effect.To crop spraying control, has the good protection therapeutic action of holding concurrently at the crop their early stage.

The present invention and existing various sterilization agent be (comprising the import bactericide) relatively, have advantages such as diseases prevention efficient height, drug effect phase are long, strong to part insect deterrent effect, stimulating growth, increase yield significantly, be described further (prescription among the embodiment all by weight) below in conjunction with example.
