Abstract
The invention relates to a suspending agent used for preventing and treating powdery mildew of cucumbers. The suspending agent comprises lentinan, plant activator proteins, thiram, garlic oil, ester polyoxyethylene ether, Chinese soapberry fruit powder, C8-10 fatty alcohols, hydroxyethyl cellulose and deionized water. The suspending agent has the advantages that the suspending agent is a compound pesticide used for controlling powdery mildew of cucumbers; the suspending agent has obvious synergistic effects and has the effect of obviously reducing the usage amount of active ingredients after lentinan, plant activator proteins and thiram are compounded; and the suspending agent has the effect of effectively reinforcing the functions of preventing and treating the powdery mildew of cucumbers, takes effect quickly, has long duration, does not affect non-target crops and has obvious yield-increasing effects on cucumbers.
Description
Technical field
The present invention relates to a kind of suspending agent for preventing and treating powdery mildew of cucumber, belonging to pesticide field.
Background technology
Lentinan is the effective active composition extracted from quality xianggu fruit body, is a kind of host immunity reinforcing agent, and lentinan has antiviral, antitumor, immunity moderation function and stimulates the functions such as interferon formation.Lentinan is the composition improving phyto-immunity, and the polysaccharide of its molecular weight more than 10,000 is main with β-1,3 glucan, containing a small amount of wood sugar and mannose.Lentinan is mainly used in field of medicaments the earliest, and that studies biopesticide along with people deepens continuously, and has at present and lentinan is used for pesticide field.
Plant activation protein is that a class of separation and Extraction from fungi has Promoting plant growth and improves the heat-stable protein exciton of its resistance.This molecular weight of albumen is 42kD, and isoelectric point is about that the current plant activation protein of 4.18. mainly screens from the fungies such as Alternariaspp, sheath blight fungus, Aspergillus flavus, botrytis, rice blast fungus, sickle-like bacteria, abstraction and purification obtains.Plant activation protein has biologically actives such as strengthening plant disease-resistant, insect protected, anti-adversity ability and Promoting plant growth.
Tmtd is a kind of bactericide with protective effect, its has a broad antifungal spectrum, mainly for the treatment of seed and soil, and the seedling blight of control Cereal smut and various crop.Also can be used for spraying, prevent and treat some fruit trees, vegetable disease.Active ingredient tmtd on the impact of environment, Bluegill LC50(48 hour mg/L) 0.23, trout LC50(48 hour mg/L) 0.13, carp LC50(48 hour mg/L) 4; Honeybee LD50(contacts) be greater than 10 micrograms/honeybee, Japanese quail LD50(per os mg/kg) 695, red ring blackbird (per os mg/kg) 300.The half life period of tmtd is 0.5 day (sand, pH6.7).
Powdery mildew of cucumber is commonly called as " white defect ", is injured the heaviest, is secondly petiole and stem, does not generally endanger fruit with blade.Their early stage, face of blade or the back side produce the rotund little amyloid plaque of white, being expanded into unconspicuous large stretch of white powder district, edge gradually, being covered with blade face, as having spread layer white powder.Erase white powder, visible blade face chlorisis, withered and yellowly to become fragile.When falling ill serious, blade face is covered with white powder, becomes canescence, until whole blade is withered.After powdery mildew infects petiole and tender stem, similar on blade of symptom, only scab is less, and powder is also few.Blade starts produce yellow point, then expand and develop into circle or oval scab, the mould layer of the raw adularescent powdery in surface.Ordinary circumstance bottom blade is more than upper blade, and vacuum side of blade is more than front.Mildew is disperseed separately in early days, after be unified into a large mildew, even can cover full leaf, have a strong impact on photosynthesis, eubolism is interfered, causes early ageing, output incurs loss.In recent years, powdery mildew creates certain pesticide resistance, this problem urgently to be resolved hurrily.
