Description
Technical field
The present invention relates to the aqueous emulsion for preventing and treating tomato disease, be specifically related to a kind of effective ingredient be SYP-3375 and garlicin for preventing and treating the aqueous emulsion of graw mold of tomato, belong to technical field of pesticide.
Background technology
Graw mold of tomato is mainly caused harm flowers and fruits, also can cause harm blade and stem.Young fruit is caught an illness heavier, and stigma and the many elder generations of petal are infected, and backward fruit shifts.Fruit is many to be extended to fruit face at fruit stem.The peel that causes a disease is canescence, soft corruption, and sick minister goes out the mould layer of a large amount of celadon, fruit abscission time serious, ossifys after dehydration.Blade is caught an illness, and how from the beginning of blade tip, scab is inwardly extended in " V " font, and first water stain shape is light brown, has the alternate stricture of vagina of taking turns of the unconspicuous depth, and time moist, scab surface can produce grey mold, and blade is withered.Stem is caught an illness, and produces water stain shape point, is extended to the most rapidly oblong, time moist, and the raw mould layer of taupe in surface, the above plant in disease portion can be caused time serious withered.Graw mold of tomato is caused by Deuteromycotina fungus, the pathogen of Botrytis cinerea infect.This pathogenic bacteria survives the winter in soil or with mycelium and conidium with sclerotium on invalid body, when condition is suitable, sprouts mycelia, produces conidium, propagate by means of air-flow, rainwater and people's production activity.Its thermophilic 20-25 DEG C of falling ill, the highest 32 DEG C, minimum 4 DEG C, strict to humidity requirement, relative air humidity starts morbidity when reaching 90%, and high humidity is held time length, and morbidity is serious.
SYP-3375 (coumoxystrobin) is a kind of methoxy acrylic bactericide that China is newly developed, effective to powdery mildew, gray mold, downy mildew, rice sheath blight disease, the highest to canker of apple fruit spore germination activity, but relatively low to canker of apple fruit mycelia growth inhibitory activity.Along with being all the kresoxim-methyl of methoxy acrylic bactericide, Fluoxastrobin, the use of pyraclostrobin spread, the resistance problem of this series bactericidal agent is more and more prominent.It addition, SYP-3375 is newly synthesized compound, being used alone relatively costly, exploitation compound synergic compositions can improve cost performance.
Garlicin (Allicin) is a kind of organosulfur compound extracted from the bulb (Bulbus Allii head) of Liliaceae allium Bulbus Allii (Allium Sativum), exists in Bulbus Allii Cepae and other alliums.Formal name used at school GIUCOSinoate.Pale yellow oily liquid body.Boiling point 80-85 DEG C (0.2kPa), relative density 1.112(20/4 DEG C), index of refraction 1.561.It is dissolved in ethanol, chloroform or ether.Dissolubility 2.5% (quality) (10 DEG C) in water, its pH value of water solution is 6.5, has grease precipitate to be formed during standing.Can dissolve each other with ethanol, ether and benzene.Unstable to thermokalite, stable to acid.By in the bulb being present in liliaceous plant Bulbus Allii, the garlic aminoacid existed under big allinase effect, convert generation.Exist in the bulb of Herba Alii fistulosi.Having strong big garlic odour, taste is peppery.
Summary of the invention
For the problems referred to above, present invention provide for preventing and treating the aqueous emulsion of tomato disease, instant effect of the present invention, holding effect are long, to non-Target crops safety.
