Abstract
The invention relates to a dimethomorph-containing thermal smoke agent for preventing and controlling downy mildew of vinyl house cucumbers. The thermal smoke agent comprises the following active ingredients: dimethomorph and azoxystrobin, dimethomorph and chlorothalonil, dimethomorph and cymoxanil, dimethomorph and metalaxyl, dimethomorph and hymexazol, or dimethomorph and enestroburin, and also comprises the following auxiliaries: an emulsifying agent, a dispersing agent, a solvent, a viscosity regulating agent, a defoaming agent and the like. The active ingredients and the auxiliaries are prepared into an oil-suspending thermal smoke agent, wherein the dimethomorph is mixed with other medicaments in a ratio of 1:3 to 3:1; and the medicaments comprise 20 to 40 percent of active ingredients. The dimethomorph-containing thermal smoke agent is specially used for thermal smoke sprayers and has special effects on the downy mildew of the vinyl house or facility-cultured cucumbers. The thermal smoke agent can also be widely used for preventing and controlling diseases such as the downy mildew, peronophythora and the like of watermelons, pumpkins, tomatoes, chillies, eggplants and the like cultured by facilities such as vinyl houses and the like, and has the advantages of high application value, and sufficiently obvious economic and social benefits.
Description
(1) invention field:
A kind of thermal aerosol that contains control such as dimethomorph plastic tunnel cucumber downy mildew that the present invention relates to, contain (E, Z)-4-[3-(4-chlorphenyl) 3-(3, the 4-Dimethoxyphenyl) acryloyl] morpholine (to call dimethomorph (dimethomorph) in the following text) dimethomorph and Fluoxastrobin, or contain dimethomorph and tpn, dimethomorph and white urea cyanogen, dimethomorph and metalaxyl, dimethomorph and Wakil, dimethomorph and Enestroburin, emulsifier, dispersant, the oil suspension thermal aerosol that solvent, auxiliary agents such as viscosity-controlling agent and defoamer are made (hot fogging concen-trate) composition.
Simultaneously, the present invention relates to use a kind of thermal aerosol and using method thereof that contains control plastic tunnel cucumber downy mildews such as dimethomorph.This thermal aerosol also can be widely used in watermelon, custard squash, tomato, capsicum, eggplant of facility cultivations such as plastic tunnel etc. and prevent and treat diseases such as downy mildew, phytophthora root rot, and using value is big, and economic and social benefit is very remarkable.
(2) technical background:
Dimethomorph (dimethomorph) is the single-minded Oomycete fungi bactericide that kills, its effect characteristics are to destroy the formation of cell envelope, all there is effect in each stage to oomycetes history of life, and is particularly responsive in the formation stage of sporangiophore and egg spore, promptly is suppressed under extremely low concentration.This medicament is widely used in vegetables downy mildew, eqpidemic disease, seedling stage damping off, black shank etc. by the fungus-caused disease control of Mastigomycotina Oomycete, inhales bactericidal activity in the tool.
Cucumber downy mildew main harm blade, stem, inflorescence tendril, become strain phase blade to catch an illness by lower blade to vertical spread, blade back produces the water soaking mode spot during their early stage high humidity in early morning, the water soaking mode scab disappeared after the morning, humidity descended, after enlarging, leaf spot lesion is subjected to the vein restriction to be polygonal, leaf front scab moves back and greenly is faint yellow, and the scab back side is yellowish-brown, and blade back scab portion produced purplish grey to black downy mildew layer when the edge was obviously moist.As untimely control, greatly to the yield and quality influence.
Cucumber downy mildew is the disease, particularly winter warm type plastic tunnel cucumber that each cucumber producing region of China generally takes place, and because of low, the high humidity of temperature of shed in winter, especially is fit to the generation of cucumber downy mildew.Run into sleety weather especially, excessive because of humidity in the canopy, be difficult for adopting traditional spray-on process control.
