Abstract
The invention relates to a pesticide composition for preventing and controlling plant nematode diseases and application thereof. The pesticide composition is prepared by compounding polyoxin, chitosan oligosaccharide, an auxiliary agent and a solvent, wherein the polyoxin and the chitosan oligosaccharide are used as active ingredients; and the weight ratio of the polyoxin to the chitosan oligosaccharide is 1:0.01-100. The pesticide composition is particularly suitable for preventing and controlling diseases of grain crops, economic crops and vegetables caused by nematode and has the advantages of reasonable mixing, good preventing and controlling effect and low cost.
Description
Technical field
The present invention relates to a kind of composition pesticide, particularly relate to a kind of synergetic pesticide composition and application thereof that comprises polyoxin and chitosan oligosaccharide.
Background technology
Plant nematode extensively colonizes on root, stem, leaf, flower, bud and the kind reality of each Plants, makes plant that various nematodosis occur.Be with the cause of disease difference of other plant that Plant nematode has and initiatively attack the characteristics that host and automatic moving are caused harm, when causing harm host plant, cause the mechanical damage except the nutrition of drawing the host with to plant tissue, the esophageal gland of Plant nematode can be secreted noxious material, it mainly is multiple digestive ferment, bring out host tissue various pathological changes occur, can make plant tissue cell's overdevelopment, form megabacterium, perhaps the dissolved cell mesoglea causes that cell decomposes, destroy cell wall, cause root and cortex to form cavity and cell death, finally make plant growth weak, yield reducation, the product qualitative change is bad, even dead.In addition, some nematodes also interact with other cause of diseases such as fungi, bacterium, virus, and common causing a disease caused compound disease, increases the weight of the generation of disease.
Crops can reach 40-50% because nematodiasis causes crop yield loss to estimate, and for example the rice root Root-knot can cause underproduction 10-20% in the generation of China southeast, southwest in recent years when serious.And for example end at the beginning of 2008, China causes harm because of pine wood nematode and causes 18.2 hundred million yuans of direct economic losses, causes forest ecological to lose 21,600,000,000 yuans.Whenever need every year to use a large amount of agricultural chemicals to carry out nematodiasis for this reason and prevent and treat to retrieve crop yield loss.In recent years, the crops for example harm on paddy rice, fruit tree, pine tree, vegetables, flowers, lawn and the diversified economy crop are more and more serious, and because people use for a long time take organic phosphor as main nematocide, nematode easily develops immunity to drugs, and causes the disease-controlling effect reduced year by year.Environmental disruption is also very large simultaneously.Therefore, need to have better effect and the environmentally friendly pesticide species of preventing and treating nematodiasis.
In addition, the applicant finds still do not have relevant polyoxin and chitosan oligosaccharide to be mixed at present and prevent and treat the play-by-play of nematodiasis both at home and abroad through retrieval.

The invention still further relates to above-mentioned composition pesticide the control plant nematode diseases or for the preparation of the control plant nematode diseases agricultural chemicals in application.
Especially, described plant nematode diseases is the nematodiasis on the crops such as paddy rice, peanut, sugarcane, vegetables, fruit.
Composition pesticide of the present invention is mainly used crops such as paddy rice, peanut, sugarcane, vegetables, fruit.Mainly on seed, sapling, rice shoot and before the sowing transplanting, use, behind the dilute with water, carry out respectively in different periods: before sowing or the transplanting, carry out soil disinfection; Seed or nursery stock are dressed seed or the nursery stock sterilization.The spraying of seeding stage root soil; Sick sapling is soaked root.
Polyoxin is a kind of novel efficient, low toxicity, broad-spectrum antibiotics series bactericidal agent.This medicine Main Function mode is the biosynthesis of interference cell wall chitin.The cell wall of some fungies of the body wall of the nematode that consists of take chitin as matrix, the chorion of line eggs and Ascomycetes, Basidiomycetes and deuteromycetes, with can expand, break, overflow cell inclusion in the part after mycelium contacts medicament, cause the death of nematode and fungi.When polyoxin directly kills nematode, worm's ovum, also can suppress the harmful bacterias such as rhizoctonia, sickle-like bacteria, mould, thereby alleviate the Combined Infection that causes because of eelworm harm.In addition, polyoxin also can be used for rice sheath blight disease, rice blast, wheat rust, head blight, Alternaria alternate, the control of the damping off of gourd, fruit and vegetable, powdery mildew, gray mold, anthracnose, stem wilt, fusarium wilt, black spot.
Chitosan oligosaccharide is a kind of novel nontoxic, high activity, good, the biodegradable plant growth regulator of Environmental compatibility, chitosan oligosaccharide can make the plant cell activation, promote plant callus to form and to the absorption of the nutriments such as nitrogen, potassium, thereby have the effect that promotes that plant cell growth is grown, can improve crop yield and improve quality.The activity of chitosan oligosaccharide energy activated plant enzyme, the inducing plant system obtains disease resistance.Thereby reduce the use of agricultural chemicals, environmental contamination reduction.This medicine Main Function mode one is the chitinase in the activated plant body, thereby improves the defence function of plant self with being, promotes the formation of plant callus, improves plant to the resistance of nematode and pathogen.The 2nd, induce the generation phytoalexin, such as chitinase, chitinase can decompose the body wall that destroys nematode, thereby kills nematode.The 3rd, can enter in the cell of nematode and pathogen, encumber pathogen transcribing from DNA to RNA, thereby encumbered the growth of nematode or the propagation of pathogen.Through test, as plant growth regulator and novel biopesticide, chitosan oligosaccharide uses crops such as leaf vegetables, green onion garlic class, beans, eggplant classes all good effect.
Composition pesticide of the present invention has following beneficial effect:
Polyoxin and chitosan oligosaccharide are used with has the extremely multi-efficiency of nematode, sterilization, enhancing plant plant resistance against diseases, and the control plant nematode diseases is had fabulous synergistic effect.The present invention is through field trial, control efficiency to groundnut root knot nematode disease reaches 72.5～93.9%, compares with single polyoxin, to the preventive effect increase by 12.3～20.5% of groundnut root knot nematode disease, compare with single chitosan oligosaccharide, to the preventive effect increase by 23.6～40.2% of peanut root-knot nematode.The two use with have efficient, quick-acting, lasting period long, delay pesticide resistance, the characteristics such as simple to operate, with low cost, environmentally safe, be the medicament of the agriculture nematodiasis of extraordinary control therefore.
