Abstract
The invention discloses a kind of containing the bactericidal composition that active ingredient is shenqinmycin and triforine, including usual auxiliaries, shenqinmycin and triforine, and the quality parts ratio of shenqinmycin and triforine is 5:1~1:1.Shenqinmycin and there is synergistic effect to pathogen fungi such as Rhizoctonia solani Kuhn toxicity after being compounded in certain proportion with triforine, is suitable for prevention by the fungus-caused crop disease of pathogen.Composition can also contain auxiliary agent, and the weight of active component is the 0.1%~40% of composition total weight, remaining is insecticides adjuvant.
Description
Technical field
The invention belongs to synergetic pesticide composition and its application fields, and in particular to one kind containing active constituent shenqinmycin
With the composition pesticide of triforine.
Technical background
Shenqinmycin (Phenazino-1-carboxylic acid) is by pseudomonas fluorescens M18 through biological culture point
A kind of antibiotic secreted has the dual function for inhibiting phytopathogen and promoting plant growth.Rice, small can effectively be prevented
Droop, blight dis-ease on the crops such as wheat, vegetables, epidemic disease, banded sclerotial blight, false smut, rice blast, downy mildew, stripe rust, sclerotium
Disease, head blight, anthracnose, gray mold, scab, leaf spot, bacterial wilt, canker, ginger plague and soil-borne disease soil treatment.
Triforine (triforine), systemic fungicide are mainly used for preventing the powdery mildew and rust of vegetables, fruit tree and cereal
Disease, rice blast, banded sclerotial blight can effectively prevent fruit and berry powdery mildew, shot hole and other diseases.It can also prevent harnessing the river
Disease in fruit storage.
Rice blast is one of important disease of rice, is infected by grey pears spore (Pyricularia grisea (cooke) Sacc.)
Cause, the significantly underproduction can be caused, the underproduction 40%~50% when serious, or even No kernels or seeds are gathered, as in a year of scarcity.Each rice region in the world uniformly occurs.This
Disease has generation in various regions, wherein being occured as with leaf portion, section portion more, the different degrees of underproduction, especially panicle blast can be caused after generation
Or section pest occur early and weigh, and can cause dead ears so that total crop failure.Germ is mainly with conidium and mycelium on straw and paddy
It is overwintering.Next year generates conidium and is traveled in rice strain by means of wind and rain, and sprouting, which is invaded people host and extended to adjacent cells, falls ill, in formation
Worry strain.The conidium that sick portion is formed borrows wind and rain to propagate, then is infected.
Rice sheath blight disease is also known as moire disease, and popular name spends sufficient stalk, rotten foot pest, features spot.It is by Rhizoctonia solani Kuhn
(Rhizoctonia solani K ü hn) infection is fallen ill, and is mostly occurred under high temperature, super-humid conditions.Banded sclerotial blight is in South Rice Region of China
Evil is serious, is one of the Major Diseases in current Rice Production.The disease prevents rice from earing, or the not plump paddy of heading is more, grain
Decline again.Bacterium is mainly overwintering in the soil with sclerotium, also can be with mycelium on invalid body or in other hosts such as weeds in field
It is upper overwintering.Sclerotium flies at the water surface and mixes with other sundries when next spring spring irrigation, and sclerotium is adhered to rice strain approximately level after rice transplanting
Leaf sheath on, condition causes harm suitable for bearing mycelia intrusion leaf sheath tissue, and aerial hyphae is infected again adjacent to plant.Rice jointing stage disease
Feelings start to increase sharply, based on disease is caused harm to transverse direction, Longitudinal Extension, before heading with leaf sheath, heading backward inclined blade, the extension of fringe neck portion.
The sclerotium that falls into the water in early days can also cause rice strain and infect again.Early rice sclerotium is the main source of infection of late rice banded sclerotial blight.
It is one of prevention corps diseases and the most effective chemical means of volume increase using chemical agent；It is anti-with no interaction
The novel pesticide of property is come to prevent corps diseases be a good solution；But one novel pesticide of exploitation needs to sieve at present
Ten thousand compounds are chosen, hundred million dollars of cost 1.2-1.5, the development cycle is 5-10, it is difficult to which the upper pathogen caught up with develops immunity to drugs
Speed；Other methods such as crop structure adjustment, different pesticide rotations etc., in actual mechanical process, it is difficult to play apparent
Effect.
Rational bactericide compounded or mixture, which has, expands fungicidal spectrum, improves control effect, extends dispenser period, reduces and use
Dose reduces poisoning risk, reduces residual, delays the advantages that generation and development of pathogen drug resistance and drug resistance, so choosing
It is maximally efficient and economic one of the method to solve the above problems to select suitable bactericide compounded or mixture；However because pesticide
The mechanism of action is complicated between mixture, and whether synergy is affected by various factors after combination, only relies on experimental result and is tested
Card, can not be expected.
Develop 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.
Shenqinmycin and the synergistic combination of triforine have not been reported.
