The present invention also relates to agricultural composition comprising the nematicide composition and fertilizer with the functions of purifying soil, raising plant resistance, providing plant with nutrients and preventing and controlling nematode and diseases.
Description
[technical field]
The present invention relates to a kind of nematicidal composition that contains nematocide and chitin class material, because the nematicide that adopts combination has nematicide and the effect that increases the immunity of plant two aspects own, therefore, the effect of control nematode is very obvious.In addition, the invention still further relates to the agriculturally useful compositions of forming by described nematicidal composition and fertilizer.This agriculturally useful compositions has purification, cleaning soil, improves the resistance of plant, and supplies with the required nutrient of crop, multiple efficacies such as pest control treatment.
[background technology]
Plant nematode is one of plant infectious cause of disease, and they extensively colonize on root, stem, leaf, flower, bud and the kind reality of each plant species, make plant that various nematodosis take place.The plant nematode overwhelming majority is the male and female similar shape, and promptly female male worm all is wire, and elongated transparent, polypide is very little.General body is long only 1 millimeter, and wide 0.05 millimeter of body will just can be seen clearly by disecting microscope.Kind of this class nematode and quantity are all a lot, and it is extensive again to distribute, and every have the place of soil and water all might exist.Also having the minority Plant nematode is that male and female are difform, and female worm resembles a pear in shape, sphere or cryptomere, and male worm still is wire.Modal as root-knot nematode, Cyst nematode, reniform nematode etc., they all are most important pathogenic nematodes.
Harmful to plant at present nematode, the kind more than 40 that has in China's discovery mainly contains rhabditis axei, root-knot nematode, cyst roundworm, pratylenchus etc.Wherein crop is endangered root-knot nematode and cyst roundworm most serious of all, the crop that is mainly endangered has cucumber, peanut, soybean, paddy rice, wheat, potato, tobacco, beet, citrus, crudefiber crop etc.The general generation of nematode just can make this class crop failure 10%～40%, can reduce 70%～80% when serious, even total crop failure, and its extent of injury has some idea of.
Because nematode is a kind of lower animal, individual tiny, but nematode polypide inside has flourishing digestive system and genital system, draws its needed nutrition in plant corpus.Nervous system, other animals of excretory system geometric ratio want simple many, generally will just can see these interiors clearly under high-power microscope.Plant nematode has very big harmfulness, cause the mechanical damage except that the nutrition of drawing the host with to plant tissue, the esophageal gland of Plant nematode also can be secreted noxious material, these materials contain multiple digestive ferment, bring out host tissue various pathological changes take place, and can make plant tissue cell's overdevelopment, form megabacterium, or cell mesoglea dissolving causing cell is decomposed, cell wall is destroyed, causes root and cortex to form cavity and cell death.Modal phenomenon is that the plant cell volume expands, and most typical is exactly the root-knot nematode formed megabacterium behind the plant of causing harm, and the result can form the knurl that differs in size " root knot " on root; After and for example similes thorne is caused harm citrus, cell wall is decomposed, the cortex of the killed root of result forms typical cavity, causes root-rot mashed at last; The nematode secretion that also has then shows had strong inhibitory effects, and root is stopped growing, and plant growing is suppressed and shows dwarfing.More than performance illustrates that the chemical action of Plant nematode secretion can finally make plant growing weak to the influence of plant cell and tissue generation, and output reduces, and the product qualitative change is bad, even dead.In addition, the nematode that has can transmitted virus, and makes plant that certain virus disease take place, and like this, has increased and enlarged the generation of virus disease, and this harmfulness also is sizable.Simultaneously, nematode also interacts with other cause of diseases such as fungi, bacterium, and common causing a disease caused compound disease, increases the weight of the generation of disease.
Whole world nematicide medicament kind has 30 kinds approximately at present, and commonly used is no more than 10 kinds, can be divided into halogenated hydrocarbon, sulfuration isosulfocyanate, carbamates and organic phosphates by its chemical constitution.The agricultural chemicals that present China is used for the controlling plant nematode mainly contains Nemacur, furans pellet, Aldicarb etc., and these agricultural chemicals are big to the person poultry toxicity, and environmental pollution is serious, even can produce poisoning.For this reason, people attempt to solve this problem by the mode of safe, for example, CN1060945A discloses a kind of nematicidal composition that contains Nemacur, it comprises for example combination of α-Nai Yisuan of Nemacur and safener, though still part solves the drug injury problem that plant is produced, its safe effect to the user is also unsatisfactory.
The nematocidal active material that also once adopted natural origin in the prior art for example microorganism secondary metabolite is prevented and treated causing harm of nematode, and commercial product arranged, for example Royal 300, Royal 350, Bioact etc. are in the control efficiency instability of these products.For example, CN85104021A discloses a kind of chitin-protein complex with eelworm-killing activity; The secondary metabolite that CN1297996A discloses a kind of microorganism-thick wall cell verticil is the mematocide of main active.In addition, about also having reported the C that adopts control fertilizer in the document: N weight ratio and employing fertilizer and chitin class combinations of substances suppress the growth of plant nematode in the soil.Referring to, for example CN1324213A, US5057141A.But the actual nematicide effect of biogenic nematocide of the prior art is unsatisfactory.For this reason, still just need safer working substance nematocide.
The present inventor has carried out deep discovering at the deficiencies in the prior art, adopt nematocide and the chitin class combinations of substances that can improve crop anti-adversity, can improve the resistivity of crop, nematode is had the synergy killing action, reach purpose nematode control.In addition, also find, above-mentioned nematicide combination is used with fertilizer and soil conditioner, can reach safe in utilization, the purpose of purification, cleaning soil, the two is used in combination, both can improve the resistance of plant, supply with the required nutrient of crop, can reach multiple efficacies such as pest control treatment again, achieve many things at one stroke, so finished the present invention.
