Abstract
The invention relates to a pesticide composition comprising the active components including (A) which is fosthiazate, and (B) which is at least one of abamectin and azadirachtin. The mass ratio of A to B is 100:1-1:50. By combining A and B, the composition has obvious synergistic effect and is used for controlling the pests on such crops as fruit trees, cotton, wheat, rice, rape, vegetables, flowers and the like, especially for controlling nematodes.
Description
Technical field
The present invention relates to a kind of Pesticidal combination, especially a kind of composition pesticide that contains fosthiazate.
Background technology
Plant nematode mainly comprises: Meloidogyne (Meloidogyne), kidney shape Turbatrix (Rotylenchulus), cyst roundworm (Heterodera (Heterodera)), root spot nematode (Pratylenchidae belongs to (Pratykenchus)).Directly searching for food of nematode can significantly reduce the absorption of plant to nutrition and moisture, and the nematode plant that searches for food is caused wound, returns the phytopathogen invasion and provides convenience.
Nematode chemical control possibility is few at present, and the control nematode concentrates on substantially and prevents the invasion and attack of nematode to plant on the agricultural.In case plant by parasitism, must be caused the infringement to plant, thereby to provide new nematoda control composition to prevent or reduce nematode damage be favourable.
And, still adopt phonamiphos, cadusafos, the contour malicious agricultural chemicals of carbofuran to a great extent at present for nematoda control, and there is very big environment secret worry, alternative low toxicity nematocide is seldom.Fosthiazate is a kind of organic phosphor low toxicity desinsection, nematocide, and is effective to a lot of harmful insects, and various nematodes are had the good activity of killing.But fosthiazate uses consumption big separately, and long-term use must bring out nematode and produce resistance, is unfavorable for Sustainable Control.
Summary of the invention
The objective of the invention is to: the safety that contains fosthiazate, the synergetic pesticide composition that use on a kind of suitable agricultural, nematode, soil insect had outstanding control efficiency are provided.
We find to have synergistic effect by the composition that comprises fosthiazate (A) and at least a biogenic pesticide (B) Avermectin (B-1) or nimbin (B-2) when preventing and treating nematodosis, with only use independent active component and can obtainable control efficiency compare, active components A and B are mixed the back use, or use compd A and B simultaneously separately, or use A and B to provide better control efficiency successively to pest.
Mixture of the present invention has synergistic function, and therefore is specially adapted to prevent and treat the parasitic nematode in parasitic nematode and soil insect, especially cereal class, vegetables, fruit, the ornamental plants that endangers plant root.
Comprise fosthiazate (A) and at least a biogenic pesticide (B) Avermectin (B-1) or nimbin (B-2) in the present composition, even a small amount of A or B are for realizing that Synergistic also is enough, A and B mass ratio are 100: 1-1: 50, preferred 50: 1-1: 10, most preferably 20: 1-1: 1.
When the preparation mixture, preferred pure active components A and B, also can use the former medicine of high-load, can also be to wherein adding other reactive compound to harmful fungoid or other insect such as insect, spider or nematode, or have the compound or the fertilizer of herbicide effect or growth regulating effect.
The present composition can be prevented and treated the pest in various crops such as cotton, vegetables (as cucumber, beans, tomato, potato and cucurbitaceous plant), barley, dogstail, oat, banana, coffee, corn, fruits, rice, rye, soybean, wheat, ornamental plants, sugarcane and the seed, as nematode, diamond-back moth, cabbage caterpillar, rice leaf roller, smaller green leaf hopper, tea geometrid etc.
The present composition is particularly suitable for preventing and treating plant nematode, for example Pratylenchidae (Pratykenchusspp), similar similes thorne (Radopholous similis), fuller's teasel stem eelworm (Ditylenchusdipsaci), the nematode (Tylenchulus semipenetrans) of partly puncturing, Heterodera kind (Heterodera spp.), ball Heterodera kind (Globodera spp.), Meloidogyne kind (Meloidogyne spp.), kidney shape Turbatrix kind (Rotylenchulus spp.), Aphelenchoides kind (Aphelenchoides spp.), minute hand Turbatrix kind (Longidorus spp.), Xiphinema kind (Xiphinema spp.), burr Turbatrix kind (Trichodorus spp.), umbrella Aphelenchoides kind (Bursaphelenchus spp.).
Preferably mixture of the present invention is used to prevent and treat the nematodosis of oil crop such as cereal class, paddy rice, wheat, fruit tree, cotton, vegetables, soybean, flowers etc., as wheat root-knot nematode, oranges and tangerines root-knot nematode, cucumber root-knot nematode, soy bean cyst roundworm, capsicum root-knot nematode etc.
The present composition can be prepared into known method and be fit to the formulation that agricultural is used, and the total content of active ingredient is 1%-90% in the preparation, preferred 5-80%, and all the other are the pesticide adjuvant composition.
Forming the effective constituents A of the present composition and B can be simultaneously (be about to A and B uses together or use compd A and B simultaneously separately), also can use A and B successively, and this moment, order was usually to the not influence of result of control.
Agricultural chemicals cooperative compositions of the present invention can be formulated as suspending agent, aqueous emulsion, microemulsion, missible oil, wetting powder, the water dispersible granules that directly to spray or to carry out soil treatment, also can be made into granule and directly carry out soil treatment.
Control crop nematode preferred dosage form is a granule.
Preparation prepares in a known way, for example prepares by reactive compound is mixed with solvent and/or carrier, if the words that need are used other pesticide adjuvant compositions such as emulsifier and dispersant.
Insecticide-applying way can take spraying, irritate root, soak root, get rid of and execute, spread fertilizer over the fields, ditch spread, spread manuer in holes etc., preferred ditch spread during the control nematode, spreads manuer in holes, irritates soil treatment such as root or soak root and handle.
Compared with prior art, the beneficial effect of the present invention's generation is: (1) is compared with single agent, and this Pesticidal combination is obvious to insect synergy, has improved control efficiency, has enlarged insecticidal spectrum; (2) can significantly reduce the field dosage, reduce the possibility that causes poisoning, reduce and produce and use cost, and can effectively reduce environmental pollution and residue of pesticide; (3) mechanism of action of active ingredient is different in the Pesticidal combination, has reduced the single selection pressure to pest, helps overcoming the disease resistance and delays the drug-fast generation speed of pest; (4) Pesticidal combination has good control efficiency to all kinds of nematodosis.
Embodiment
