Abstract
The invention provides a biogas liquid compounded fungicide for preventing and treating gray mold. The fungicide contains the following ingredients in percentage by weight: 99.5-99.8% of biogas liquid and 0.2-0.5% of fungicidal composition, wherein the fungicidal composition is prepared from procymidone and difenoconazole which are in the weight ratio of 2.8: 1. According to the fungicide, the advantages, namely rapidity and durability in disinfection, of chemical pesticides and the advantages, namely safety and no residue, of the biogas liquid are integrated, active antimicrobial ingredients in the biogas liquid are sufficiently utilized, the dosage of the pesticides is reduced, and environmental risks are reduced; moreover, nutritional ingredients in the biogas liquid can be directly absorbed and utilized by fruit and vegetable crops, the growth of the crops can be promoted, and the disease resistance of the crops can be enhanced; the effects on preventing and treating the gray mold of fruits and vegetables can reach over 85%, so that the fungicide obtained through compounding is very efficient.
Description
Technical field
The invention belongs to pesticide production technology field, be specifically related to a kind of natural pond liquid compound disinfectant of preventing and treating gray mold.
Background technology
Developing rapidly of livestock and poultry breeding industry in recent years, makes swine manure wastewater pollute the Main Factors that day by day becomes water pollution, and biogas technology, as one of effective way that solves that feces of livestock and poultry pollutes, is developed rapidly.In order to make full use of the contained multiple organotrophy composition containing of the natural pond liquid producing after feces of livestock and poultry anaerobically fermenting the effect that improves its disease-resistant, insect-prevention, research and development can instead of chemical agricultural chemicals environmentally friendly efficient pesticides, be that instead of chemical agricultural chemicals is to solve an important channel of the problems such as the existence of pollution of agricultural products harm humans and environmental destruction.Natural pond liquid, as a kind of generally acknowledged broad spectrum " biological pesticide ", from mechanism, can not bring resistance problem, can not cause to environment the pollution of similar chemical fertilizer, agricultural chemicals yet.Although anaerobic fermented liquid has the effect of desinsection, yet find in actual agriculture production, this effect needs just can play obvious effect for a long time.The slower feature of this drug effect makes to promote the use of anaerobic fermented liquid in agricultural and has run into very large difficulty, is difficult to be applied on a large scale.
And common agricultural chemicals has efficient characteristic, but in long-term use procedure, easily form very harmful pesticide residue, atmosphere, water quality, soil are caused to severe contamination, to human health, cause significant damage.
If can be by both mutual supplement with each other's advantages, be about to anaerobic fermented liquid and agricultural chemicals and carry out according to a certain percentage proportioning, by rational mixing, to retain the nontoxic of anaerobic fermented liquid on the one hand, the advantage of noresidue, to retain the characteristic of agricultural chemicals efficient insecticide on the other hand, meanwhile, also will avoid the high residue of agricultural chemicals.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of natural pond liquid compound disinfectant of preventing and treating gray mold, and this sterilant has remarkable prevention effect to the gray mold of vegetable crop, and pesticide dosage is extremely low, and environmental pollution is less.
Technical scheme provided by the invention is a kind of natural pond liquid compound disinfectant of preventing and treating gray mold, comprises the component of following weight percent: natural pond liquid 99.5～99.8%, fungicidal composition 0.2～0.5%; Described fungicidal composition comprises that procymidone and difenoconazole form, and its weight ratio is 2.8:1.
Above-mentioned fungicidal composition is made emulsion or pulvis by formulation difference, in every L emulsion, contains fungicidal composition 50～900g, 1%～45% solvent (containing emulsifying agent), 1～20% auxiliary agent, and all the other are water.Above-mentioned per-cent is the volume percent of this composition in emulsion.The component of pulvis and weight content are: 10～90% fungicidal composition, 9～75% sorbent materials or filler, 1～20% auxiliary agent.
Due to the difference of component concentration, emulsion can be divided into suspension agent, aqueous emulsion and microemulsion, and pulvis can be divided into wettable powder and water dispersible granules.Above-mentioned formulation, is all to adopt conventional production process formulated by fungicidal composition, conventional variety when related emulsifying agent, solvent, auxiliary agent, sorbent material/filler is preparation agricultural chemicals in component.Such as emulsifying agent, can select agriculture breast 33#, Nongru-700 # or agriculture breast 602# etc., solvent can be selected dimethylbenzene, DMF or ethanol etc., and sorbent material/filler can be selected diatomite, white carbon black or perlite etc., and auxiliary agent can be selected organosilicon, poly-di-alcohol etc.
The fermented liquid that described natural pond liquid is fowl and animal excrement, three months above fermented liquids that refer generally to ferment, its pH value is 6.5～8.0, wherein ammonia-state nitrogen accounts for 73～79% of total nitrogen content, nitrogen (N), phosphorus (P
2o
5), potassium (K
2o) weight ratio is 0.1～0.3:0.05～0.2:0.1～0.3.
After natural pond liquid is sprayed on plant, wherein contained nutritive ingredient, as amino acid, Plant hormones regulators,gibberellins, indolylacetic acid, is absorbed on plant surface, and these nutritive ingredients are absorbed growing up healthy and sound of rear promotion plant body.Healthy plant body can play effective resistance, defence to disease and pest.Improved like this disease-resistant, insect-prevention ability of plant.In the liquid of natural pond, a contained composition part with disease-resistant, insect-prevention effect is because the penetration performance of medicament and the sorption of plant enter in plant body, and along with juice in plant body is transmitted to each position of plant, make whole plant body juice be with within a certain period of time poison, but harmless to plant.After having inhaled toxic plant juice, insect thorn causes being poisoned to death.Another part rests on plant surface, and insect contacts after this part of composition, from body surface, enters the normal physiological metabolism process of body internal interference insect or destroys some tissue of insect, causes that insect is poisoned to death.Or the volatilizable composition in the liquid of natural pond volatilizes gas, insect sucks poisonous gas and is poisoned to death through respiratory system.
Preparation method:
1) natural pond liquid preparation: by three months above fowl and animal excrement fermented liquids that normally ferment, filter, remove after granule foreign, regulating pH value is 6.5～8.0, and wherein ammonia-state nitrogen accounts for 73～79% of total nitrogen content, nitrogen (N) phosphorus (P
2o
5) potassium (K
2o) weight ratio is 0.1～0.3::0.05～0.2:0.1～0.3.
2) preparation of fungicidal composition: be that 2.8:1 mixes by weight by procymidone and difenoconazole, technique is mixed with pulvis or emulsion routinely.
3) natural pond liquid and fungicidal composition are pressed to proportioning mixed preparing, be the natural pond liquid compound disinfectant of preventing and treating gray mold.
When natural pond of the present invention liquid compound disinfectant is used, directly fillingly enter in atomizer, be evenly sprayed onto vegetable plant strain leave dual sides and bud, lobus cardiacus part, keep wet and do not drip.
Compared with prior art, the present invention has following beneficial effect:
1) advantage of the quick and durable sterilization of chemical pesticide and the advantage of the safe noresidue of natural pond liquid have been merged in the present invention, take full advantage of active antibacterial component in the liquid of natural pond, have reduced agricultural chemicals using dosage, have reduced environmental risk.
2) in the liquid of natural pond, nutritive ingredient can directly be absorbed by vegetable crop, can promote plant growth and strengthen its resistance against diseases.
3) this product can reach more than 85% the prevention effect of gray mold, very efficient.
