Abstract
The invention relates to a bactericide for controlling cucurbits powdery mildew. The bactericide comprises lentinan, plant activator protein, thiophanate methyl, lignosulfonate, a wetting agent F, sodium bicarbonate and attapulgite. The compound pesticide for controlling cucurbits powdery mildew has a remarkable synergistic effect after lentinan, plant activator protein and thiophanate methyl are compounded, the dosage of effective ingredients is remarkably reduced, the prevention and control effects on cucurbits powdery mildew are effectively improved, and the bactericide takes effect quickly, has a long lasting period and does not have any influence on non-targeted crops.
Description
Technical field
The present invention relates to the bactericide for preventing and treating cucurbits powdery mildew, belonging to pesticide field.
Background technology
Cucurbits powdery mildew is commonly called as " white hair " various melon crop all there is generation, is injured seriously with cucumber, pumpkin, custard squash and muskmelon.Powdery mildew mainly occurs on blade, is secondly, on stem and petiole, generally not endanger melon.When just falling ill, blade there is white starch point, expand rounded white powder spot gradually, when condition is suitable for, scab expands, connect in flakes, become irregular large stretch of white powder macular area, edge, and whole blade can be covered with, afterwards in canescence, sometimes scab surface produces many pores, and blade turns yellow, and matter is crisp, lose photosynthetic function, generally do not fall leaves.Cucurbits powdery mildew, in a short time just can rapid spread once occur, and brings larger loss to melon production.
Thiophanate-methyl inhales low toxicity bactericide in a kind of broad spectrum activity, has interior suction, preventive and therapeutic action.Belong to hypotoxicity bactericide.Former medicine rat acute LD50 of passing through mouth is 7500 mgs/kg, and rat acute is greater than 10000 mgs/kg through skin LD50.Rabbit skin and eyes are had no stimulation.Be 11 mg/litre (48h) to carp LC50, crouching fish LC50 is 8.8 mg/litre (48h).To birds, honeybee low toxicity.Thiophanate-methyl has to top property conduction function, has preventive and therapeutic action to multiple diseases.Inhibitory action is had to tetranychid and pathogenic nematode.
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.
