Description
Technical field
The invention belongs to the nuisanceless fertilizer technical field, be specifically related to a kind of tithonia plant pesticide composition.
Background technology
Plant can run into various damage by disease and insect in the occurring in nature process of growth, fungus disease particularly, its kind is many, and disease is serious, and, dark fund sick etc. sick such as sick, the red gold of gold is that the disease of control occurs generally, comparatively to be difficult on many crops, bring huge loss to agricultural production, mainly occur in the parts such as tender seedling, bud, the tip of crop, when serious, blade is withered, curling, the browning look, withered.A large amount of chemical means that use are prevented and treated at present, yet domesticly for the medicament of preventing and treating powdery mildew, mainly contain the unicity of for many years medication of methyl and the particularity of chemicals, be easy in use operating personnel and ecotope be made to serious harm, and have in a large number residual, easy-clear, do not cause injury to edible people, and therefore country is own through banning use of highly toxic pesticide, greatly develop the green non-pollution vegetables, so be badly in need of developing the public nuisance-free agricultural chemicals that low toxicity is even nontoxic.Causing harm of farmland weed often causes a large amount of underproduction of crops every year.Use chemical herbicide to remain the Main Means of current weed control, but, due to a large amount of and unreasonable use chemical herbicide, caused the problems such as environmental pollution, residue of pesticide and herbicide resistance, be subject to extensive concern.Therefore, exploitation is efficient, the new herbicides of low toxicity, low-residual, becomes problem in the urgent need to address.Find bioactivator from plant, and then the environmentally friendly agricultural chemicals of development of new, be the hot fields of the outer research of Present Domestic.
China is large agricultural country, and about 400,000,000 m2 of area occur the crop diseases and pest crop smothering throughout the year, and annual the need produced and used 800,000 tons, agricultural chemicals, and agricultural chemicals has become indispensable factor in agricultural production.Being widely used of agricultural chemicals, although production development has been played to important function, also occurred pesticide resistance problem such as insect pest, disease, to the pollution of environment and in agricultural and animal products residual and accumulation problem, injure natural enemy, destroy balance of nature, cause pest resurgence problem etc.This development to novel pesticide has proposed higher requirement.Especially, since entering 21 century, along with the cry of people's uphold nature, protection of the environment, concern food security is day by day surging, harmless boilogical agricultural chemicals industry and biological control area research have obtained rare opportunity to develop.
Biotic intrusion is considered to cause the one of the main reasons of the interior ecosystem degradation of world wide and the loss of biodiversity.Instruction plant is by replacing native plants and then setting up the integrality that single species group threatens the ecosystem.Invasion mechanism and the impact of determining exotic plant are most important to predicting its spreading rate, formulation prevention and control and even ecological reconstruction (ecologicalrestoration) measure.At present, for the reasonable utilization of adventive instruction plant, report is also arranged, the Activities of Some Plants extract all possesses desinsection, antibiotic characteristic.But not yet form the commercialization pesticidal preparations, market in urgent need is a kind of is conducive to environmental protection, effectively sterilization, weeding, and can be applicable to the large nuisanceless bactericidal and herbicidal medicament of plant of producing.Will be at invasion habitat choose reasonable plantation substituted plant source pesticide by this research, thus realize its continuous and effective is controlled and technical support.
