Abstract
The invention belongs to the field of agricultural bactericides, and provides a bactericidal composite comprising penconazole and thiophanate-methyl, wherein, the weight percentage of the penconazole and the thiophanate-methyl is 0.1-80: 15-80. In addition to effective components, other additives and carriers are added to be prepared into a suspending agent, a wettable powder and a water dispersible granule, which is applied to the disease control of fruit trees, melons and wheat, the bactericidal composite is characterized by curing and protection effects on crop pests, wide bactericidal spectrum, remarkable effect, extremely strong bactericidal power, low service cost and no damage to crops and environment.
Description
Technical field
The invention belongs to the pesticide sterilizing technical field, relate to a kind of bactericidal composition, active ingredient is made up of penconazole and thiophanate-methyl, is used for the disease control of fruit tree, melon, wheat class, is particularly suitable for the control of pear scab, watermelon powdery mildew and wheat powdery mildew.
Background technology
Penconazole is a kind of triazole type high activity bactericide with interior suction, treatment, protection, eradicant action, suppresses the sterol demethylation; work at fungus spore germination with between stage of invasion; have superpower interior absorption, drug effect height simultaneously, to crop safety, the characteristics that the lasting period is long.
Thiophanate-methyl is a kind of broad-spectrum germicide, and the mechanism of action divides thereby influence bacterium for disturbing the formation of imitative hammer body in the mycelia division, has protection and therapeutic action.
Pear scab; claiming the pear tree shot hole again, is the main disease of pear tree, and regular meeting causes heavy losses; from all falling ill to the fruit tree mature period behind the fallen flowers; all chlorenchymas on the harm pear tree are in recent years because long-term poor efficiency medicament such as mancozeb, the zineb etc. of using cause the disease resistance more and more serious; not only cost increases; and do not have positive effect, along with the increase of resistance and hazard area, cause the outburst situation at China's north and south pear tree planting area year after year.
Watermelon, wheat powdery mildew, because spread speed is fast, host range is wide, takes place throughout the year, is easy to generate resistance especially, common control medicament such as tpn, mancozeb, use has not had any control efficiency separately, and causes the disease resistance seriously to increase.
Preventing and treating powdery mildew, the present main flow way of scab is to release new active ingredient, but the new component cost is too high, is difficult for large tracts of land and promotes the use of.At present the most effective way is exactly to carry out between the agricultural chemicals of different sterilization mechanisms compositely mutually, has not only delayed the resistance generation, and has reduced usage amount, has improved control efficiency, is to prevent and treat powdery mildew, the most effective way of scab at present.
Summary of the invention
The objective of the invention is to propose a kind of can effectively prevent and treat fruit tree, melon, wheat class fungal disease is remarkably productive; crop pest had obvious treatment and protective effect; disease be difficult for to produce resistance, lasting medicine and have a synergistic function contain penconazole and thiophanate-methyl bactericidal composition.
