Abstract

The invention provides a pesticide reagent containing edible oil and organic silicone and a new usage and a preparation method of the pesticide reagent. By the adoption of the pesticide reagent containing the edible oil and the organic silicone, 69.5-86.7% of plant diseases and insect pests such as powdery mildew, gray mold, acarids, aphids and thrips of crops can be prevented and controlled, so that the dosage of pesticide is reduced, and the harmful effect of the pesticide on the environment is relieved.

Description

The agricultural chemicals reagent mixed containing edible oil and organosilicon and purposes
Technical field
The invention belongs to control of crop disease field, especially, belong to the control utilizing the damage by disease and insect such as a kind of biological control powdery mildew, gray mold, aleyrodid, aphid, mite class, thrips.
Background technology
Along with the fast development of Protected Production of Vegetables, China has also become the maximum country of crop facility cultivation area, intensive vegetable filed system is one and closes or semi-enclosed ecosystem, environment is relatively stable, temp. and humidity is high, and the vegetables four seasons cultivate, and plant is relatively tender, be very beneficial for surviving the winter and multiplying of disease worm, wherein the mini pest such as thrips, aleyrodid, aphid, mite class and the multiple diseases such as powdery mildew, gray mold occur especially serious.
Peasant household, for preventing crop disease and insect, to abuse, many pesticide growns, takes shelter from rain and the environmental condition of shading also delays clearing up of pollutant simultaneously, there is serious agricultural product security hidden danger.
The use of rise to agricultural chemicals with pollution-less agriculture proposes new requirement, clearly prohibit the use severe toxicity, high poison, high residue and carcinogenic, teratogenesis, mutagenesis agricultural chemicals, and strict control has all been done to the consumption, working concentration, use age etc. of available agricultural chemicals.Therefore, the green Prevention Technique of alternative agricultural chemicals is the demand that pollution-less agriculture further develops.
Summary of the invention
The present invention seeks to the damage by disease and insect such as powdery mildew, gray mold, aphid, aleyrodid, mite class, thrips for crop, propose that a kind of preparation is newly simple, the green medicament of environmentally safe; Another object of the present invention is the embody rule method proposing to utilize the prevention and elimination of disease and pests in green agriculture is produced of this medicament.At present, about organosilicon and edible oil mixture effect be reported in the also not relevant report in agricultural insect pests control aspect.
The object of the invention is achieved through the following technical solutions.
The method of application organosilicon and edible oil controlling crop diseases and insect pests, the method is carried out according to the following steps:
(1) the pre-organosilicon of preventing disease and pest and the solution preparation of edible oil: the edible oil (soybean oil, corn oil, olive oil, rapeseed oil, palm oil, ready-mixed oil, peanut wet goods, or their mixture) adding 60g in 6 grams of organosilicons is fully stirred; Edible oil solution is mixed with the water dilution of 20 ± 1L, for subsequent use.
(2) the edible oil solution preparation of prevention and elimination of disease and pests: add 180-360g edible oil by 18-36g organosilicon, fully stir; Edible oil solution is mixed with the dilution of 20 ± 1L water, for subsequent use.
(3) to the prevention of crop disease and insect: be sprayed to plant before liquid generation damage by disease and insect step (1) prepared, executed spray 1 time every 10-14 days, connect spray 5-10 time, be sprayed to plant by the consumption of 60-80L/ mu and use;
(4) to the control of crop disease and insect: medicine liquid spray step (2) prepared is to the plant that damage by disease and insect occurs, within 10-14 days, execute spray once, connect spray 5-7 time, by the positive and negative of consumption even spraying to plant leaf and the surrounding of stem stalk of 60-100L/ mu.
On the other hand, the invention provides a kind of purposes of novel agent, specifically, provide organosilicon and edible oil making the purposes on reagent such as control crop powdery mildew, gray mold etc.
On the other hand, organosilicon and edible oil is provided to make the purposes on control crop acarid, aphid, thrips reagent.According to described purposes, wherein, the part by weight of organosilicon and edible oil is 1:4-1:20.Preferably, the part by weight of organosilicon and edible oil is 1:10-1:20.
According to described purposes, wherein, edible oil is a kind of or mixture of above-mentioned edible oil in soybean oil, corn oil, olive oil, rapeseed oil, ready-mixed oil, peanut wet goods eating at home oil.
Organosilicon is a kind of Prof. Du Yucang, with a kind of high molecular polymer that silicon atom and oxygen atom are main chain in structure.Owing to forming the silicon-oxide structure of main chain, there is stronger chemical bonded refractory, therefore the general organic polymer of the molecular proportion of Organosilicon Polymers to heat, oxidation stability many.Although organosilicon mechanical property at room temperature and other materials variances little, but its Physical and mechanical properties under high temperature and low temperature is outstanding, temperature at-60 to+250 DEG C of repeatedly alternations and its performance is unaffected, thus Organosilicon Polymers can in this temperature province Long-Time Service.Some Organosilicon Polymers more normally can use at being low to moderate-100 DEG C.Again owing to there being dipole effect in silicone molecules, it can effectively cushion and weaken the impact of external electrical field, thus has protective effect to the hydroxyl connected on the silicon atoms, makes it the erosion not being subject to physical factor or chemical reagent.Organosilicon of the present invention can be the organic silicone oil of any kind, such as containing hydrogen silicone oil, dimethicone, vinyl silicone oil, hydroxy silicon oil, polymethylphenyl siloxane fluid, methoxyl group silicone oil, water-soluble silicon oil, phenyl silicone oil, silicone emulsion, amido silicon oil, dryness silicone oil, volatile silicone oils, viscous silicone fluid, high vacuum diffusion pump oil.Preferably, organosilicon is that ethyoxyl modification gathers trisiloxanes, the agricultural silicone active agent of trisiloxanes.
The invention has the beneficial effects as follows:
1, after organosilicon and edible oil are mixed with control liquid by the present invention, to the preventive effect before crop morbidity evil with about 80%, reduce harm, reach the object of protective plant; The present invention adopts organosilicon edible oil to prevent and treat the damage by disease and insect such as the powdery mildew of crop, gray mold and acarid, aphid, thrips, has the control efficiency of 69.5-86.7%, with the harmful effect alleviating Pesticide use amount and cause environment.The present invention, by directly utilizing the environmental friendliness prevention and elimination of disease and pests medicament of means development of new, has good theory and practice meaning, receives significant ecological benefits and social benefit.The organic silicone oil that the present invention uses easily buys easily preparation in life of farmers, and a kind of non-harmful product of cheapness.This agent has good application prospect.
