Its application method features that said composition is directly injected in to plant body. Its advantages are low dosage, high and durable effect and applying it for all weathers.
Description
The present invention relates to a kind of injectable composition and method of preventing and treating plant pest.Exactly be a kind of control herbaceous plant, the composition and the using method of especially preventing and treating the banana disease insect pest.
The main distinction of herbaceous plant and woody plant is stem, and herbal stem does not have xylem, does not resemble the stem of woody plant hard.Banana is the tall and big herbaceos perennial of a kind of plant, and its stem is divided into true stem and false stem.True stem claims stem tuber again, imbeds in the soil or partly and bassets; False stem on the ground, by leaf sheath tight superimposed composition, it acts on the terrestrial stem of similar woody plant, the false stem of the banana of growing up is higher than 2m, plant can be higher than 3m.
The main disease of banana has leaf spot, scab, anthracnose, and main insect pest has weevil, hands over arteries and veins aphid, tortrix moth etc.The banana disease insect pest is mainly carried out chemical control with agricultural chemicals at present, and its application method generally adopts the blade face to spray.Because the plant of banana is tall and big, and the cured matter layer in Banana Leaf surface is thicker, smooth surface, and drop is difficult for adhering to, and influences control efficiency.The shortcoming that spray on the blade face is the rate that the scatters height of agricultural chemicals, not only causes waste, and contaminated environment, influences dispenser personnel's health, resembles this tall and big plant of banana and sprays also very difficult.Although people can improve the adhesive rate of medicament on the blade face by the physical property of improving medicament, but because banana is grown in the rainy torrid zone, subtropical zone, spray also easily by rain drop erosion on the blade face, not only cause the repetition dispenser, also often because the former thereby dispenser in time of weather, lose dispenser opportunity, causing harm of uncontrollable damage by disease and insect causes the underproduction.When insecticide is sprayed on the blade face, also injure natural enemy easily.
The application method of other crops also has ground or underground dispenser, space stifling, extremely indivedual with the methods of smearing.The shortcoming of ground or underground dispenser is that active ingredient is easily decomposed by edaphon, and the surface water is also easily polluted.Be convenient to the tall and big fruit of plant, forest dispenser though the space is stifling, also have with the blade face and spray same shortcoming.Semar technique has overcome the shortcoming of blade face spraying and ground, underground dispenser, but medicament is slower by the speed that plant tissue absorbs, and therefore, the drug effect performance is also slower.Simultaneously, the medicament of smearing also exists by the problem of rain drop erosion.
Although there is above problem in above-mentioned various application method, except that semar technique, the dispenser work efficiency of other the whole bag of tricks is all higher, still is widely used so far.For overcoming the shortcoming of above-mentioned various application methods, existing people carried out research to the application method of woody plant and explored, as the method for acupoint burying solid method (CN1132018A) and xylem injection liquid pharmaceutical.Because the woody plant xylem is harder, injection needle is difficult to insert, and therefore, also has the people to carry out research aspect instrument used for injection and explores (CN88211060, CN2087867, CN2160192, CN2155662).But it is reported that injection widespread usage not as yet on the woody plant extermination of disease and insect pest does not still have report on herbaceous plant.
The objective of the invention is to select for use a kind of composition and new insecticide-applying way to carry out the herbal extermination of disease and insect pest, to bring into play the advantage of various application methods, overcome its shortcoming, promptly to improve the availability and the control efficiency of agricultural chemicals, reach higher dispenser work efficiency again, but all dispensers under any weather condition make the peasant can be because of weather not former thereby lose best dispenser opportunity.For reaching this purpose, selected direct injection for use, agricultural chemicals is directly entered in the herbaceous plant body, to improve agricultural chemicals availability and control efficiency.
For direct injection is implemented, need research applicable to the composition that is injected directly in the plant corpus, after being used, it can reach higher control efficiency, and the purpose of poisoning does not appear again.Composition for injection has a kind of unitary agent or complex preparation that belongs to insecticide, miticide, bactericide or weed killer herbicide etc. at least.Comprise copper agent, organic sulfur, organic phosphor, organic nitrogen, organotin, carbamate, triazole type, imidazoles, nitrogen heterocyclic ring, the pesticide active ingredient of compounds such as clam worm poison, network amine copper as the copper agent class, copper sulphate, copper oxychloride, the generation of organic sulfur class gloomy amine, mancozeb, S-Ethyl ethylthio sulfonate, the chlorophos of organic phosphates, flolimat, chlopyrifos, three second aluminium phosphates, the azacyclotin of organic tin, three phosphor tins, the Propamocarb of carbamates, carbosulfan, Methomyl, the alkene azoles alcohol of triazole type, Tebuconazole, the Prochloraz of imidazoles, the Imidacloprid of nitrogen heterocyclic ring class, the dimehypo of nereistoxin etc.Weed killer herbicide is applicable to plant complete stool or local putting to death.The agricultural chemicals of different cultivars can be as required single with or use with.
Main points of the present invention are the necessary higher organic solvents of soluble in water or organic solvent, particularly polarity of composition that are used to inject, as methyl alcohol, ethanol, acetone, acetic acid, dimethyl formamide (DNF) etc.And only be dissolved in the composition of non-polar organic solvent, must have certain interior suction or conductive performance, and can make missible oil or emulsion.The composition of water-soluble or polar solvent, elder generation's water or polar solvent dissolving during preparation, water only is dissolved in the composition of non-polar solven then, can be made into the parenteral solution that is diluted with water to emulsion state after the missible oil again.
Key problem in technology of the present invention is that the osmotic pressure of parenteral solution must be slightly less than or near the osmotic pressure of banana caulo tissue.On this basis, select active constituent content; According to the needs of control efficiency, determine the soup consumption again.Like this, both guaranteed result of use, and made crop avoid poisoning again.In view of the above, the pesticide effective component content that is used to inject is 0.01-95%, and pesticide effective component content is 0.01-50% in the parenteral solution, and optimum content is 0.1-10%, and the parenteral solution consumption is every strain 0.1-200ml, and optimum amount is 1-50ml.
To use parenteral solution always and directly inject in the plant corpus with common medical or veterinary syringe, common or special injection needle during dispenser, be generally stem or the branch of plant.Also available absorption of making needle-like the plant stem or the synthetic material of soup directly insert in the protected plant corpus, drug slow is discharged.According to artificial subjective wishes, can be at one or more positions of plant, carry out plant whole body or local dispenser from the diverse location of plant.Can inject in stem when carrying out the whole plant control, can be during local control in branch or blade injection.The injection site of banana disease insect pest is that banana is set overhead 10-200cm place of false stem, and the optimum position is the 40-150cm place overhead.
Composition that the present invention is selected and injection thereof can reach specific leaf area and spray that medication is few, preventive effect is high, the lasting period in the herbal extermination of disease and insect pest such as banana, its outstanding advantage is that any weather all can dispenser, and its shortcoming is that drug effect performance specific leaf area sprayed slightly slow 1-2 days.
Following example can illustrate:
Select for use the banana disease insect pest that more serious plot takes place throughout the year and do the test of pesticide effectiveness, establish the clear water spraying and be experimental control.Each example all establishes injection treatment and processing is handled or smeared to other processing method relatively as spraying, and spraying is handled and smeared processing can be according to conventional method preparating liquid and dispenser, 100 kilograms of spray-on process mu spraying liquids; Parenteral solution is according to top said method preparation.Test plot soil property, liquid manure situation unanimity, 125 strains of every mu of plantation banana.Example 1: the carbamate fungicide Propamocarb is prevented and treated sigatoka test example:
