Abstract
The invention provides a pesticide composition containing carvacrol and cnidium lactone and application thereof, belonging to the field of pesticides. The pesticide composition containing carvacrol and cnidium lactone is composed of the following active components in parts by weight: 1 part of carvacrol and 0.5-2 parts of cnidium lactone. The pesticide composition containing carvacrol and cnidium lactone has the remarkable synergistic interaction effect, and the prevention and treatment effects of powdery mildew can be improved; the pesticide composition is composed of the two effective components with different action mechanisms and the cost is relatively low; and compound medicaments are plant sources and a pesticide residue problem does not exist, so that the risks of phytotoxicity can be greatly lowered.
Description
Technical field
The present invention relates to the composition pesticide containing carvacrol and Osthole and application thereof, belong to pesticide field.
Background technology
Powdery mildew is caused by the Erysiphaceae in fungi, mostly be ectoparasitism, whole or the large portion of mycelium be exposed to host plant, the tender tip, bud and surface, and produce the macroscopic white powder thing be made up of mycelium, conidiophore and conidium in a large number, therefore named powdery mildew.Powdery mildew is widely distributed in the whole world, and dicotyledon of causing harm is particularly general.The main powdery mildew of China has by the microbial Cereal powdery mildew of standing grain white powder; The powdery mildew of the various plants such as melon, the beans caused by Siberian cocklebur monofilament shell, crudefiber crop; The grape powdery mildew caused by grape snag shell; The powdery mildew etc. of the Flowers of Rosa caused by rose monofilament shell.Therefore, the control of powdery mildew is the important topic of pesticide field research.
At present, the chemical control of powdery mildew mainly adopts chemical bactericide to prevent and treat, conventional as Duo Mai can (taking tetraconazole as main component), nitrile bacterium azoles etc.Along with the increase of chemical pesticide frequency of utilization and usage amount, its potential drawback also displays gradually, has that toxicity is higher, residue of pesticide exceed standard, germ produces serious pesticide resistance etc. to medicament as adopted chemical bactericide.Along with people are to the attention of biocontrol of plant disease, the effect of biopesticide in controlling powdery mildew work is more and more important.Biopesticide has that toxicity is low, environment compatibility good, and the biopesticide of different mechanism of action also played a kind of effect alleviating resistance risk by producing the pesticide species developed immunity to drugs in the past.
Coumarin kind compound Osthole, chemical name is 8-(3-methyl-2 cyclobutenyl) methyl ether umbelliferone, it is the main component in Carrot family plant frutus cnidii, also be the root welding technology of Imperatoria ostruthium, circle Radix Angelicae Sinensis, Angelica pubescens, bolt wing celery, rutaceae is anistree, the root skin of Calusena lansium, the active component of the acrial part of single leaf rue etc.Medically there is anticancer, antimutagenesis, agriculturally there is the report of killing pests and suppressing bacteria.
Application number be 200410069127.5 patent of invention " Osthole and built composition for preventing and controlling crop powdery mildew thereof " disclose Osthole single dose and preventing and treating the application in crop powdery mildew with the bactericide compounded bactericide obtained of the Antifungi ergosterols such as nitrile bacterium azoles, triazolone, penta oxazolone, but, it is higher that frutus cnidii single dose is used alone cost, the chemical pesticides such as itself and triazolone are carried out composite, also exists that toxicity is higher, residue of pesticide exceed standard and germ produces the defects such as serious pesticide resistance to medicament.
Summary of the invention
