Description

Bactericidal composition containing fluorine bacterium mite ester and eugenol
Technical field
The invention belongs to synergetic pesticide composition fields, and in particular to one kind contains active constituent fluorine bacterium mite ester and clove tree The composition pesticide of phenol.
Technical background
Fluorine bacterium mite ester, english common name: flufenoxystrobin, test code number: SYP-3759 is a kind of methoxyl group Acrylic bactericide, by the electronics transfer in Cytochrome B cl to cromoci, to inhibit the breathing of mitochondria. The compound is used alone higher cost and is easy Induced resistance and generates, to reduce the service life.
Eugenol, english common name Eugenol, chemical name Coryophyllic acid, eugenol doctor It is used for antibacterial, anti-inflammatory on medicine, agriculturally can be used for preventing and treating the crop diseases such as crop gray mold, banded sclerotial blight, sigatoka.
Leaf muld of tomato is on the leaf of tomato, stem, flower, fruit, the symptom that can all occur, but is commonly to occur On blade, initial stage vacuum side of blade occur it is some move back green statin, the later period becomes the mould layer of irregular shape of grey or black purple, and blade is just Green flavescence is moved back at corresponding position in face, and when serious, withered crispatura often occurs in blade.In terms of the sequence of morbidity, often under plant Portion creeps up, temperature from 9 DEG C to 34 DEG C, cause of disease can growth and development, the optimum temperature of development is 20~25 DEG C.Most When thermophilic degree and humidity larger (relative humidity is 80% or more), it is only necessary to can generally fall ill within 10 days to half a month.
Leaf muld of tomato main harm blade also endangers stem, flower and fruit, blade morbidity, initial stage face of blade when serious There is yellow green, the unconspicuous spot in edge, the mould layer of canescence occurs in leaf back, and rear mould layer becomes light brown to dark brown；Humidity When big, blade surface scab can also grow mould layer.Disease is often first fallen ill by lower blade, is gradually crept up, when falling ill serious Mould layer is covered with blade back, leaf rolling, and whole strain blade dries up in yellowish-brown.Also it can produce similar scab in tender stem and carpopodium, flower Device morbidity is easy to fall off.Fruit morbidity, base of fruit nearby or on fruit face form black circle or irregular patch, and hardening recess cannot It is edible.This sick Fulvia fulva category pathogen Cladosporium fulvum (Fulvia fulva (Cooke) Cif.) by fungi Deuteromycotina, Caused by alias (Cladosporium fulvum (cooke) Cif.) infects.Germ is mainly residual in diseased plant with mycelium or mycelia block It is overwintering in vivo, seed or intradermal overwintering in kind with mycelium can also be attached to conidium.When next year environmental condition is suitable for, produce Raw conidium borrows air-flow to propagate, and invades from the stomata of blade back, can also invade from the part such as sepal, bennet, and enter ovary, It hides on kind of skin.
Germ is overwintering in invalid body with mycelium or mycelia block, and the surface of the seed or mycelia can also be attached to conidium It hides overwintering in kind of skin.When next year condition is suitable for, overwintering mycelium generates conidium from invalid body, is drawn with air-flow propagation First aggression is played, in addition, the seed that sowing is carried disease germs can also cause First aggression.The disease has repeatedly to be infected again, after germ sprouts, from host The stomata of leaf back invades, and mycelia spreads in iuntercellular, and generates haustorium and protrude into and absorb water into the cell and nutrient, forms disease Spot.When environmental condition is suitable for, a large amount of conidiums are generated on scab again, progress is constantly infected again.Germ can also be from sepal, bennet Stomata intrusion, and can enter ovary, hide on kind of skin.
Application chemical agent is one of prevention and treatment most effective chemical means of phytopathogen；With the novel pesticide of not cross resistance Carrying out controlling plant diseases is a good solution；But one novel pesticide of exploitation needs to screen a chemical combination up to ten thousand at present Object, hundred million dollars of cost 1.2-1.5, the development cycle is 5-10, the speed that the upper pathogen for being difficult to catch up with develops drug resistance；It is other Method such as crop structure adjustment, different pesticide rotations etc., in the actual operation process, are difficult to play apparent effect.
Exploitation new product fungicide is expensive, the period is long, and in contrast, exploitation is efficient, less toxic, low-residual with research Compounding have with mixture invest small, lead time it is short and by attention both domestic and external, it is numerous and confused to increase development dynamics.
The synergistic combination of fluorine bacterium mite ester and eugenol has not been reported, the mechanism of action and work of fluorine bacterium mite ester and eugenol With feature difference.
