Abstract
The invention discloses a kind of composition pesticide comprising captan and fluazinam, the weight ratio of active component captan and fluazinam is 30 in the composition pesticide:1‑1:10, preferably 10:1‑1:1, the composition pesticide of the present invention can be by adding the regular dosage form species that auxiliary element is prepared into pesticidal preparations, select any in missible oil, wettable powder, water dispersible granules, suspending agent etc., composition pesticide of the invention is particularly suitable for use in preventing and treating graw mold of tomato.
Description
Technical field
The invention belongs to composition pesticide field, and in particular to be a kind of pesticide sterilizing containing captan and fluazinam
Composition and its application.
Background technology
Gray mold is open country, protecting field crop is common and compares a kind of fungal disease of difficult preventing and treating, belongs to low temperature and high relative humidity
Type disease, 20-30 DEG C of growth of pathogenic bacteria, when environment temperature in 20-25 DEG C, humidity 90% above is for the disease high-incidence season, grey mold
Disease belongs to fungal disease, flower, fruit, leaf, stem can fall ill caused by the pathogen of Botrytis cinerea infects.Gray mold sick seedling color is shallow, blade, leaf
Handle morbidity be in canescence, water stain shape, organization softening to rot, there is grey mold on surface during high humidity.Young stem is how nascent in petiole base
Irregularly water logging spot, becomes and rots, hangs and contract or roll over quickly, and last sick seedling, which rots to wither, dies of illness.The disease is a kind of typical gas
Disease is passed, can be propagated with air, current and farming operation.During actual disease control, it is difficult to take effective measures
Thoroughly cut off source of infection；In the case where pathogen invades, it is also difficult to utterly destroy pathogen, such as medicament is sprayed, it is difficult to solved
Pathogen in air and dew；And individually smoke canopy, it is impossible to emphasis is solved on the invalid bodies such as sick leaf, disease fruit or internal cause of disease
Bacterium.
Captan is a kind of lower toxicity broad spectrum protection bactericidal pesticide, can prevent and treat the crops such as apple, pears, strawberry, grape
Multiple diseases, with prevention effect is good, poisoning is small, the appropriate effect for stimulating plant growth using also having.Its main function machine
Reason is to block disease fungus respiratory, can also reduce the content of atriphos in pathogen to prevent the mitogenetic spore of germ
The bulk storage of son.It is mainly used in spraying, can also makees infusion product after seed treatment, harvest, is carried out before sowing or before plant at soil
Reason.For preventing and treating the scabs of fruit tree, vegetables, flowers and other industrial crops etc., downy mildew, powdery mildew, anthracnose, grey mold
Disease, early blight, late blight etc..The activity of the compound is good, and still, it is sometimes and unsatisfactory in low rate of application.Its
There is preferable prevention effect to a variety of fungal diseases, but when preventing and treating bacterium and fungal disease simultaneously, it seems not enough.And
Captan applicating history is long, and some pathogens have produced certain resistance to the action of a drug to captan.Therefore, other efficient sterilizings are selected
It is to resist resistance, delaying drug resistance development that agent is compounded therewith, extends a kind of important channel of its service life.
Fluazinam is new substituted phenyl amines, the broad-spectrum germicide developed by Japanese Shi Yuan industry companies, belongs to environment
The bactericide kind for having market prospects of friendly, its mechanism of action is mitochondrial oxidation phosphorylated uncoupler, by resisting
Spore germination, mycelia break through, growth and sporogenesis and the infection processs for resisting all stages.The fungicidal spectrum of fluazinam is very wide,
Its effect is often due to conventional protecting bactericide, in addition to bactericidal activity, fluazinam also shows the mite killing to red spider etc.
Activity.Fluazinam be mainly used in grape, apple, citrus, soybean, potato, wheat, tomato, cucumber etc. make use it is a variety of
Disease, good prevention effect is respectively provided with to gray mold, scab, late blight etc., in addition, fluazinam is to Cruciferae clubroot
Also there is remarkable preventive effect, also have good preventive effect to the paddy rice samping off as caused by rhizopus.
Single pesticide activity component is for a long time continuously using can cause resistance risk and the increased risk of consumption, and be unfavorable for
The continuity in Pesticide use life-span, by agriculture chemical compounding screening obtain compounding rational composition pesticide be reduce Pesticide use amount,
Delay after drug-fast important channel, different pesticide activity components compounded, to typically exhibit different interactions, typically
For summation action, synergistic effect and antagonism, the composition pesticide of compound synergic is less, but it can improve actual preventing and treating effect
Really, Pesticide use amount is reduced, is the important means of integrated control.At present, it is not yet found that being compounded on captan and fluazinam
Relevant report.
The content of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide, a kind of prevention effect is good, cost is low, can delay
The Synergistic composition pesticide that the pathogen resistance to the action of a drug is produced.
Another object of the present invention is to provide the composition pesticide to be used to prevent and treat corps diseases especially tomato ash
The purposes of mildew.
The technical scheme is that be accomplished by the following way：
A kind of composition pesticide, its active component mainly includes captan and fluazinam, wherein, the weight of captan and fluazinam
Amount is than being 30:1-1:10.
Further, the weight ratio of active component captan and fluazinam is preferably 10 in the composition pesticide：1-1:
1。
Further, the gross weight percentage composition of active component in the composition is 1- in composition pesticide of the invention
