The present invention also provides a kind of cover crop to avoid the method for disease and insect pest, by the order of being wished arbitrarily by bactericidal composition of the present invention or process crop, crop propagating materials or crop growth environment cover crop and avoid disease and insect pest simultaneously.
The invention provides a kind of composition of the environment for the treatment of crop propagating materials and the crop organ grown subsequently or plant growth.Can be used as seed dressing treatment of plant propagation material, particularly seed (fruit, stem tuber, cereal) and plant cutting (such as rice) to resist infecting of germ on seed and pestinfestation and the crop pathogenic appeared in soil and insect.The salient point of bactericidal composition of the present invention is to be tolerated admirably by plant and environmentally friendly.
Term " crop propagating materials " is interpreted as all parts with fertility referring to as thing, such as, can be used for the seed of breeding plant, and asexually propagated plant material such as cutting or stem tuber.Here can it is mentioned that, such as seed, root, fruit, stem tuber, bulb, rhizome and plant local.The germination plant transplanted after germinateing from soil or after emerging and effective plant also can be mentioned.Before transplantation, by whole or local impregnation process plant propagation material, this young plant can also be protected.
The infringement to crop that major part is caused by noxious plant pathogenic bacteria, as far back as seed, after memory period and seed are sown into soil and during plant germination or after germinateing, is invaded and harassed and just be there occurs.This stage is crucial especially because just the root of growing plant and tender shoots responsive especially, even small infringement also can cause the death of whole strain plant.By process plant seed, to prevent and treat noxious plant pathogenic bacteria be known for a long time and be the theme updated.But it is not to find the problem solved in a satisfactory manner that process seed also brings a series of.Therefore, need exploitation protection seed and the method for germination plant, it can be exempted and additionally uses crop protection products more after planting or after plant germination.In addition, also need the amount optimizing reactive compound used, thus can provide best protection to seed and germination plant, to prevent plant pathogen from encroaching on, and reactive compound used can not damage plant itself.
The method that crop propagating materials especially seed is used or processed bactericidal insecticidal activity composition, mixture and its composition is known in the art, comprises the seed dressing of propagating materials, dressing, pelletized and dipping method.
In propagating materials processing procedure, active component should be made to be uniformly distributed and to be attached to seed.Process can by crop propagating materials as the thin layer preparation containing active component on seed be dressed seed, and its original size and/or shape identifiable design, become intermediateness (as dressing), then becomes thick-layer (as (such as load agent is as clay with multiple layers of different materials; Different preparation is as other active components; Polymer; With colouring agent) together with pelletized, its seed original-shape and/or size cannot identify again.
Seed treatment can be carry out unseeded seed, and unseeded seed refers to be make plant germination and be grown to object, in the results of seed with to carry out between planting seed seed whenever in field.
Unseeded seed is processed to the behavior not comprising and active component is applied to soil, but to be included in planting process be that all of target use behavior with seed.
Preferably processed before planting seed, thus pretreatment can be carried out with composition to the seed broadcasted sowing.Specifically, preferred by seed pelleting or by seed-pelleting in compositions-treated of the present invention.Process as a result, the active component in said composition is attached on seed, thus can be used for disease and/or insect pest and control.
Composition of the present invention is applied to seed with itself or suitable formulation.Preferably, seed is processed at steady state, thus makes process not cause any infringement.Usually can to gather and any time between sowing carries out to the process of seed.
Usually must be noted that during seed treatment, the germination that the amount of the amount and/or other additive that are applied to the present composition of seed is chosen as can not affect seed maybe can not damage gained plant.
Composition of the present invention is for treatment of plant propagation material, and particularly the seed of paddy rice, rape, cotton, wheat, barley, soybean, corn, peanut is particularly advantageous.
To damaging the control of plant pathogen of plant after seedling mainly through carrying out with crop production compositions process soil and plant acrial part.Owing to considering that crop production compositions is on environment and the impact that may bring of human and animal's health, thus make great efforts to reduce use the amount of reactive compound.
Bactericidal composition of the present invention can be used for the environment of plant growth.
The environment of plant growth refers to the supporter that crops can be made to take root, grow, such as: soil, water etc., concrete raw material can use such as sand, float stone, vermiculite, diatomite, agar-agar, gelling material, polymer substance, asbestos, wood chip, bark etc.Preferred soil.
The example of soilborne aquacultural fungal pathogen comprises Alternaria (Alternariaspp.), Ascochyta (Ascochytaspp.), Botrytis cinerea (Botrytiscinerea), Cercospora (Cercosporaspp., ergot (Clavicepspurpurea), standing grain cochliobolus (Cochliobolussativus), Colletotrichum (colletotrichumspp.), Epicoccum (Epicoccumspp.), F.graminearum schw (Fusariumgraminearum), rice dislikes seedling chain spore (Fusariummoniliforme), fusarium oxysporum (Fusariumoxysporum), fusarium moniliforme (Fusariumproliferatum), fusariun solani (Fusariumsolani), dimension glue chain spore (Fusariumsubglitinans), Helminthosporium (Helminthosporiumspp), avenge rotten microtorr bacterium (Microdochiumnivale), Penicillium (Pencilliumspp), Phoma (Phomaspp.), wheat class nuclear cavity bacteria (Pyrenophoragraminea), rice blast Pyricularia Sacc. (Pyriculariaoryzae), Rhizoctonia solani Kuhn (Rhizoctoniasolani), Rhizoctonia cerealis (Rhizoctoniacerealis), Sclerotinia (Sclerotiniaspp.), Septoria (Septoriaspp.), , silk axle smut (Sphacelothecareilliana), Tilletia (Tilletiaspp.), meat spore core coral bacterium (Typhulaincarnate), hidden bar smut (Urocystisocculta), Ustilago (Ustilagospp.) or Verticillium (Verticilliumspp.).
Soil germ has rhizoctonia solani, sickle-like bacteria, pythium spp, phytophthora, bacterium of dampinging off, root rot, pythium spp, botrytis cinerea, soft-rot fungi etc.In the ordinary course of things, soil germ can produce a large amount of thalline, as long as condition is grown favourable to pathogen growth and host is susceptible, germ just also can infect host by amount reproduction, under susceptible host exists, these germs just can enter the lasting pathogenic phase, the amount reproduction diffusion along with the continuous cropping of crop, but afterwards nutrient be consumed or soil condition is as unfavorable to germ in temperature, humidity etc. time, germ can enter resting stage again.When susceptible host does not exist, soil-borne disease bacterium also can survive in soil, except soil germ has widely except host range, can also survive, have saprophytic competitive ability be undivided with it on the root table face of non-host or the broken branches and fallen leaves.But different germ is discrepant, almost can survive indefinite duration in soil as pythium spp.
The method of medicament is used in soil, such as liquid preparation be diluted in water or do not dilute the medium method in rice seedling bed of root or the seedling being directly applied to plant corpus, method granule is disseminated in the root of plant corpus or the rice seedling bed of seedling have prior to seeding pulvis, water dispersible granules etc. are sprayed in soil and with the method that mixes of soil entirety, is sprayed on after pulvis, water-dispersible grain dilution agent in implantation hole, seed furrow before sowing or before serike body, then carries out the method etc. sowed.
