Abstract
The invention relates to an oil-smoke agent of a microbial pesticide of bacillus and a preparation method thereof. The oil-smoke agent is a product prepared by the steps of: shearing and uniformly dispersing bacillus thuringiensis subsp kurstaki raw powder, a dispersing agent, a thickening agent, an emulsifying agent, an antifreezing agent and a solvent; and then grounding by a grinder until 90 percent of materials achieve fineness less than 5 micrometers; an finally uniformly stirring. When in use, the oil-smoke agent is quantificationally delivered into a fuming pipe to be mixed with high-temperature high-speed air flows into micrometer-grade droplets which are sprayed out by a smoke sprayer; and the micrometer-grade droplets are uniformly precipitated in different direction of each position of a target, thereby the oil-smoke agent has good precipitation effect and high preventing and curing efficiency; in addition, the oil-smoke agent has strong adhering force for the target, high rain washing resisting capacity, high affinity between the droplets and the target, longer duration, economic medication, convenient use, quick effect, sprays without adding water and is especially suitable for the forest pest control of forest zones with inconvenient traffic, few water source, precipitous hillsides and high woods and the forest pest control of closed conditions, i.e. greenhouses, storages, orchards, and the like.
Description
Technical field
The present invention relates to fume agent of a series bacillus microbial pesticide and preparation method thereof.
Background technology
Bacillus be research at present both at home and abroad at most, output is maximum, the quasi-microorganism agricultural chemicals that is most widely used, to some important agriculture and forestry damage by disease and insect, has good control efficiency as diamond-back moth, cabbage caterpillar, rice leaf roller, pine caterpillars, fall webworm, poplar caterpillar, gypsymoth and looper, powdery mildew, bacterial wilt, fusarium wilt etc.Such product forms mainly contains aqueous suspension agent and wetting powder at present, and these two kinds of formulations in use need dilute with water, but a lot of local water source that lacks, especially mountain area and arid tract, and in the forest zone time-consuming the taking a lot of work of artificial ground control, difficulty is bigger, effect is undesirable, and adopt the aircraft control, and soup adhesion and anti-evaporating ability are relatively poor, and the water evaporates fogdrop diameter diminishes, cause drift, influence result of use, and the aircraft cost is higher, is not suitable for the small size control.Because the greatly developing of industrialized agriculture, existing formulation can not well be applicable to the control of greenhouse disease insect pest in addition, also should develop easy to use, the lasting period long, preventive effect pesticides new formulation preferably.
Summary of the invention
The objective of the invention is at above-mentioned present situation, aim to provide and a kind ofly have new formulation, and have the fume agent and preparation method thereof of the microbial pesticide of bacillus of bactericidal and insecticidal activity.
The implementation of the object of the invention is, the fume agent of microbial pesticide of bacillus is made up of following components in weight percentage:
Former powder 5～35% dispersants 1.5～5.0% of bacillus
Thickener 0.2～3% emulsifier 3～10%
Antifreezing agent 2～7.5% solvents 49.8～80%,
Described bacillus is that bacillus thuringiensis Kustak subspecies, bacillus thuringiensis subsp israelensis, bacillus thuringiensis, bacillus thuringiensis are intended a kind of in walking first subspecies, bacillus subtilis or the Bacillus cercus,
Described dispersant is sodium lignin sulfonate, calcium lignosulfonate, NNO, MF or draws back one or more mixture in the powder,
Described thickener is one or both the mixture in aerosil, xanthans, aluminium-magnesium silicate, bentonite or the attapulgite,
Described emulsifier is two or more the mixture in alkylol APEO, sorbic acid fat, castor oil polyoxyethylene ether or the alkylphenol polyoxyethylene,
Described antifreezing agent is an ethylene glycol,
Described solvent is one or more the mixture in paraffin oil, white oil, kerosene, diesel oil, soya-bean oil, cottonseed oil or the castor oil.
With percentage by weight is that 0.2～3% thickener joins in 48～80% the solvent and is uniformly dispersed, add 2.5～5.0% dispersants, 3～12% emulsifier, 1～10% antifreezing agent and the former powder of 5～35% bacillus then successively, after being uniformly dispersed, shearing grinds by sand mill, material fineness to 90% reaches below the 5 μ m, stir again, get fume agent.
The present invention is dispersed in the former powder of bacillus in the solvent with suitable flash-point and viscosity, adds the preparation that other auxiliary agent is processed into the certain specification requirement again.This preparation is delivered to quantitatively the moment of mixing with the high temperature and high speed air-flow in the fuming pipe by fog machine during use, being injected into immediately in the atmosphere and volatilizing rapidly and form diameter is several microns droplet, can fill the air for a long time and be suspended in the atmosphere, diffusion in the crop clump, infiltration voluntarily, be deposited in uniformly on the different azimuth at each position of target, deposition effect is good, prevents and treats the efficient height; Strong to target adhesive force and resistance of rainwater washing against ability, affinity is strong between fume agent formed oiliness droplet of when atomizing and the target, and the long lasting period is arranged; Than ground routine spraying work efficiency height, lower than aircraft ultra low volume spraying control cost, medication economy, easy to use, it is fast to produce effects; Spraying need not converted water, especially be fit to have inconvenient traffic, water source difficulty, the hillside is precipitous, forest is tall and big forest zone forest pest control, and green house, warehouse, orchard etc. is than the extermination of disease and insect pest under the airtight condition.
