Technical field
The invention belongs to agrochemical field, particularly relate to the nematicidal composition that comprises Paecilomyces lilacinus and carbosulfan.
Background technology
Nematode has another name called worm, belongs to invertebrate Nemathelminthes Nematoda, and the nematode hazard of plant symptom that is caused that causes harm is taken as Disease Processing over a long time.Compare with pathogenic microorganisms such as fungi, bacterium, viruses, pathogenic nematode has initiatively trend and thrusts the host, and shifts the characteristics that cause harm voluntarily with lancet.The causing harm of nematode, be not only and draw plant nutrition and cause that the underproduction and quality descend, and the plant roots cell transition is increased becomes goiter and tumor, loses the ability of absorption nutrient and moisture, and plant is declined extremely; In addition, causing harm of nematode, also can cause plant to suffer the attack of pathogen more easily and cause crop that disease takes place.
Though the control of nematodosis has obtained bigger progress, also there is certain problem.The consciousness that mainly shows integrated control is thin, puts undue emphasis on the importance of chemical pesticide, has ignored the reasonable utilization of other prophylactico-therapeutic measures; Monocrop continuous cropping, cropping index are high, or the unreasonable of chemical fertilizer use, and cause the trend that being of root knot nematode disease increase the weight of year by year, up to the present, form commercialization production and be widely used in the nematode biological prevention and control agent in land for growing field crops very few both at home and abroad.
The chemical agent that is used to prevent and treat root knot nematode disease has fumigation type, like Celfume, chloropicrin and D-D mixture etc.Also have; Like carbofuran, Aldicarb and Isofenphos methyl; A collection of chemical agents such as phonamiphos, Nemacur, gram line pellet, phoxim, Mi Leer and carbosulfan are processed into the nematicide formulation at present; And obtained good effect aspect preventing and treating in the root knot nematode disease of crops such as peanut, tobacco, sugarcane, cucumber, traditional Chinese medicine, at present, the nematocide of widespread usage also has the last ten thousand, metham-sodium, dazomet, lythidathion and dithiocyano-methane etc. both at home and abroad.
The bacterium that parasitizes root-knot nematode has Pasteurella,, puncture Pasteur bacillus, Pseudomonas fluorescence; Bacillus sphaericus, bacillus subtilis, bacillus thuringiensis,Bt, rhizosphere bacteria has preventive effect to Meloidogyne incognita; Can reduce the root footing, increase root system, it is heavy to increase root.
Paecilomyces lilacinus can effectively be prevented and treated root-knot nematode (Meloidogynespp.) and SCN (Heterodera sp.), to the ovum parasitic rate of Meloidogyne incognita up to 60%～70%.Paecilomyces lilacinus is is all prevented and treated usefulness to multiple nematode, and its host has root-knot nematode, SCN, golden nematode, golden nematode, is biological prevention and control agent (Amoncho etal, 1995 of the optimum future of control root-knot nematode; Angieri et al, 1997; Khan et al, 1988,1992,2000).Because this bacterium can adapt to different climatic conditions, and line eggs is had higher parasitic rate, can effectively control soil nematodes quantity, obviously reduce harm, be widely used in the production practices.At present, the nematologist of nearly 70 countries in the world prevents and treats plant nematodes such as root-knot nematode, SCN with it, and has obtained preventive effect preferably.
In recent years, Research in China person has also done a large amount of biological and ecological methods to prevent plant disease, pests, and erosion research to this bacterium, also confirms that this bacterium has higher parasitic rate to root-knot nematode, can effectively control the quantity of root-knot nematode in the soil, obviously reduces harm.Paecilomyces lilacinus has just reduced the illness that other pathogens of host plant cause to a certain extent to inhibition or the antagonism of microorganism on every side, better plays the biological and ecological methods to prevent plant disease, pests, and erosion effect.There is research to show that also this bacterium can also produce the metabolite of multiple biologically active.
Carbosulfan, english common name carbosulfan, chemical name: 2; 3-dihydro-2; To be that carbofuran is low poison derivative for 2-dimethyl benzofuran-7-base (dibutylamino sulphur) methyl carbamate, carbosulfan, is the inhibitor of cholinesterase; Have tag, stomach toxicity and systemic action, the various pests such as aphid, mite, wireworm, colorado potato beetle, tealeaves cicada, oriental fruit moth, apple skin worm that is used to prevent and treat crops such as oranges and tangerines, fruit tree, cotton, paddy rice.Various nematodes had the good activity of killing.Insecticidal spectrum is wider, and aphid, citrus rust mite etc. is all had very high killing effect; Instant effect promptly played a role after the dispenser in 20 minutes.But use consumption big when this agricultural chemicals exists independent nematicide too, effect is undesirable, and problems such as being easy to generate pesticide resistance is used in long-term single agent.
