Abstract
The invention discloses a compound pesticide containing boscalid and kasugamycin and an application of the compound pesticide, and belongs to the technical field of compound pesticides. The compound pesticide contains 0.1-50% of boscalid and 0.1-50% of kasugamycin. The compound pesticide containing boscalid and kasugamycin is compounded by boscalid and kasugamycin, has a very high synergism effect, and has a good effect on controlling rice blasts; a control rate of the compound pesticide can reach above 95%; and the cost can be reduced by above 50% compared with exclusive use of kasugamycin.
Description
Technical field
The invention belongs to technical field of compounded pesticide, be specifically related to a kind of Recompounded pesticide and application thereof containing Boscalid and kasugarnycin.
Background technology
Rice blast is one of three large diseases of China paddy rice.Rice blast cause of disease claims grey pears spore, belongs to Deuteromycotina fungi.Mainly cause harm blade, stem stalk, fringe portion.Because the period of causing harm, position difference are divided into seedling pest, leaf pest, joint pest, panicle blast, grain pest.This disease threatens greatly Rice Production, and its degree that causes harm has difference because kind, culture technique and weather conditions are different, general underproduction 10%-20%, and the heavy 40-50% that reaches, local field even has no harvest.It is caused harm generally, often causes heavy loss, and even No kernels or seeds are gathered, as in a year of scarcity.The control conventional control medicament of rice blast is the chemical agents such as tricyclazole, Isoprothiolane, these chemical classes agricultural chemicals, and action target spot is single, along with long-term use, exists and occurs drug-fast risk.
Boscalid is the Novel tobacco acid amide fungicides of being succeeded in developing by BASF AG, can be used for various crop and prevent and treat the multiple fungal diseases such as gray mold, and to the resistance bacterium of other medicaments, also effectively it passes through the breathing of the oxygen that suppresses succinic acid matrix, thereby hinders the energy metabolism of pathogen to present bactericidal activity.Test of pesticide effectiveness demonstration, Boscalid has good control efficiency (Chi Huiwei, Li Zhinian, Liu Changling, fine-chemical intermediate, 2007,37(4) to rice blast: 14～16).The shortcoming of Boscalid is that use cost is higher, and if use for a long time as single dose, pathogen may produce resistance to it.
Kasugarnycin is the conventional medicament of control rice blast.Kasugarnycin disturbs the esterase system of metabolism of amino acid; thereby affect the synthetic of protein; suppress mycelia elongation and cause granulating; but on spore germination without impact; there is protection, treatment and stronger interior absorption; easily absorbed by mycelia and conduction rapidly in its body; suppressing mycelial growth grows; its result for the treatment of is more remarkable; the various bacteria of crop and the desirable medicaments of fungal disease such as control vegetables, melon and fruit and paddy rice; but kasugarnycin is as biopesticide, have that cost is higher, slow, the shortcoming such as the lasting period is short takes effect.
Summary of the invention
The problem existing for prior art, the object of the invention is to design provides a kind of containing Boscalid and the Recompounded pesticide of kasugarnycin and the technical scheme of application thereof.This Recompounded pesticide is to the control efficiency of rice blast is good, quick-acting soon, persistence is long, cost is low.

Described a kind of Recompounded pesticide containing Boscalid and kasugarnycin, the content that it is characterized in that kasugarnycin is 4～8%, the content of Boscalid is 10～20%.
Described a kind of Recompounded pesticide containing Boscalid and kasugarnycin, the content that it is characterized in that kasugarnycin is 5～7%, the content of Boscalid is 12～16%.
The application of described a kind of Recompounded pesticide containing Boscalid and kasugarnycin in control rice blast.
Above-mentioned a kind of Recompounded pesticide containing Boscalid and kasugarnycin can be made any formulation allowing on the Recompounded pesticides such as water dispersible granules, aqueous suspension agent, wetting powder.While making formulation, the reagent of employing is and well known to a person skilled in the art and common agents do not repeat at this.
Together with above-mentioned a kind of Recompounded pesticide containing Boscalid and kasugarnycin is composite with kasugarnycin by Boscalid, there is very strong synergistic effect, good to the control efficiency of rice blast, can reach more than 95% through its control rate of field trial; Than using separately kasugarnycin cost more than 50%.
The proportioning relating in the present invention is the percentage by weight of the pure material of active ingredient.
