Description

A kind of contain active component hundred can with the bactericidal composition that presses down mould azoles
Technical field
A kind of active component hundred that contains of the present invention can relate to a kind of bactericidal composition with synergistic function with the bactericidal composition that presses down mould azoles; This bactericidal composition is applied to agricultural plant chemoproection field, and said composition shows extremely strong antibiotic and bactericidal activity to harmful fungoid in agricultural or gardening.
Technical background
In recent years, China's fruits and vegetables cultivated area enlarges rapidly, and annual production constantly increases; In the storage transportation that fruits and vegetables are sold from gathering to; Because compound the infecting of multiple fungi can cause that multiple storage disease takes place, and causes to rot in the back of adopting of fruit, vegetables, brings about great losses.So,, fruit, vegetables in time carry out chemicals treatment after gathering, and be to prevent and reduce agricultural product to rot, prolong the effective measures of storage shelf life.
Domestic and international application mainly contains benzimidazole in the fresh-keeping chemical preservative of postharvest fruit and vegetable, sodium ortho-phenylphenate class, biguanides salt, imidazoles etc. at present.Benzimidazole germicide (Te Keduo suspending agent) acts on the tubulin of thalline, plays the effect of sterilization through the mitosis that suppresses fungi.Antimicrobial spectrum is wide, has control, treatment and eradicant action., green mold bacterium blue or green to oranges and tangerines, anthrax bacteria, the resin germ is all effective.But because the action site of medicament is single, germ develops immunity to drugs to this type medicament easily.And it is invalid to black rot, brown rot, sour germ.In oranges and tangerines preservation and freshness practice, use benzimidazole germicide to handle fruit for a long time, the pesticide resistance accumulation of germ is strengthened; Drug effect descends significantly; Some are adopted the important pathogen in back, like head mold, chain lattice spore, epidemic disease is mould, the inhibitory action of rotting also not have that causes such as mould, Mucor.Sodium ortho-phenylphenate since service life for a long time, citrus is blue or green, green mould pesticide resistance also occurred to it.On behalf of kind, imidazoles Prochloraz is arranged and is pressed down mould azoles, effective to penicilliosis, green mould, anthracnose, blossom-end rot and black rot, but invalid to sour rot.Hundred can get; Belonging to the biguanides salt, is a kind of contact killing type protective fungicide, and mainly biosynthesis and the cell membrane function to the lipids of fungi works; Suppress the formation of spore germination, germ tube elongation, appresorium and mycelia, be one type and tag and preventative bactericide.Can effectively prevent and treat citrus powdery mildew, anthracnose, ring spot, scab, leaf spot, spot defoliation.Superior to oranges and tangerines sour rot, blossom-end rot preventive effect, but invalid to black rot.
Since 1993; Press down mould azoles (Wan Lide, it is mould to wear azoles), Prochloraz (Shi Baoke) fruit fresh-keeping particularly the citrus corrosion protection fresh-keeping aspect obtained effect preferably; And this type of antisepsis antistaling agent low price, imidazoles bactericide have become most popular main antisepsis antistaling agent.But in recent years, oranges and tangerines storage period sour rot takes place to increase the weight of year by year, and oranges and tangerines storage period disease to press down mould azoles, Prochloraz has produced certain resistance.Therefore, be badly in need of delaying the oranges and tangerines germ imidazoles bactericide is developed immunity to drugs, solve the problem that the oranges and tangerines sour rot increases the weight of year by year simultaneously, with the problem of guaranteeing that citrusfruit storage safety and numerous citrus farmers' synergy increase income.
Using chemical agent is the most effectively one of means of control phytopathogen.Coming controlling plant diseases with the novel pesticide that does not have cross resistance is a good solution.But, develop a novel pesticide at present and need screen 10,000-1.2 ten thousand compounds, expensive 1.2 hundred million-1.5 hundred million dollars, the construction cycle is 5-10, is difficult to catch up with the speed that pathogen develops immunity to drugs.Other method such as crop allocation are adjusted, different agricultural chemicals is rotated etc., in the process of practical operation, are difficult to really play obvious effects.
Reasonably chemical bactericide is composite or be mixed and have the expansion fungicidal spectrum; Improve control efficiency, prolong the optimum period for applying fertilizer, reduce dosage, reduce poisoning, reduce residual, delay fungi drug resistance and advantages such as drug-fast generation and development, so select suitable bactericide compounded or to be mixed be one of the effective method the most that addresses the above problem.
Exploitation new product bactericide price is constantly soaring, and by contrast, exploitation is efficient with research, low toxicity, low-residual composite be mixed that to have the investment lead time short and receive attention both domestic and external, strengthen the development dynamics one after another.The effective necessary condition of drug combination is not have cross tolerance between the activating agent.
Iminoctadine class and imidazoles bactericide are variant in control spectrum and control efficiency, and the effect characteristics are also different with mechanism.Can also not appear in the newspapers with the combination that presses down mould azoles about hundred.
