Abstract
The invention discloses a kind of containing effective component be octyl trichlamide and fluorine bacterium mite ester bactericidal composition, the mass parts ratio of including usual auxiliaries, octyl trichlamide and fluorine bacterium mite ester, octyl trichlamide and fluorine bacterium mite ester is 15:1~1:1, preferably than for 9:1~3:1.Octyl trichlamide and there is synergistic effect to pathogen fungi such as Cladosporium fulvum after compounding in certain proportion with fluorine bacterium mite ester, is suitable for prevention and treatment by the fungus-caused crop disease of pathogen such as leaf muld of tomato.
Description
Technical field
The invention belongs to synergetic pesticide composition fields, and in particular to one kind contains active constituent octyl trichlamide and fluorine bacterium mite ester
Composition pesticide.
Technical background
Octyl trichlamide is a kind of environment-friendly type amino acids high molecular polymer fungicide, the organosilicon of composition containing synergy and mew
Class sterilization factors are high-tech of new generation, environment-friendly type, high-efficiency broad spectrum, less toxic fungicide, can generate ionization in aqueous solution,
Strong electropositive is contained in hydrophilic group part, and absorption is usually in all kinds of bacteriums of negative electricity, virus to inhibit bacterium, virus
Breeding solidifies germ protein, is the denaturation of germ enzyme system, in addition the film that polymer is formed plugs this part microorganism
Ion channel makes its death by suffocation immediately, to reach optimal bactericidal effect, broad-spectrum has absorbability and extremely strong
Permeability also has upward, downward, biaxial flexural member effect, has and protect, treat, rooting out, raising four big functions, thin to killing
Fungal disease is once completed.
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.
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 (Fulviafulva (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.
Octyl trichlamide and the synergistic combination of fluorine bacterium mite ester have not been reported, and the mechanism of action and effect of octyl trichlamide and fluorine bacterium mite ester are special
Point is different.
