Description
Technical field
The present invention is a kind of compounded preparation of pesticide, specifically a kind of bactericidal composition that contains polyoxin and carbendazim.
Technical background
Fungi is topmost phytopathogen, and the plant disease more than 70% all is by fungus-caused, and because of its paathogenic factor complexity, difficulty of prevention and cure is very big.In recent years, along with the adjustment of rural area pattern of farming, the planting fruit trees area constantly increases, and the also aggravation thereupon of the occurrence degree of many fungal diseases has caused enormous economic loss on the fruit tree.
Apple is the fruit variety of China's cultivated area maximum, but because fungal diseases such as ring rot of apple take place seriously, and be difficult to control, make China orchard worker all suffer enormous economic loss every year, the economic loss that only causes because of ring rot of apple harm in China every year is up to more than 3,000,000,000 RMB according to statistics.At present, because the orchard worker uses old medicament as using medicaments such as for many years thiophanate methyl, mancozeb through preventing and treating always, resistance rises very fast, preventive effect constantly descends, it is more and more heavier to cause fungal disease such as ring spot to take place, and the bactericide kind of seeking new preventive effect excellence seems very urgent.
Carbendazim belongs to benzimidazole germicide, and main formation by spindle in the mitosis of disturbing fungi influences its tissue division and kill pathogenic bacteria.Carbendazim has protection and therapeutic action, and the multiple diseases that comprises ring rot of apple that sac fungi, basidiomycetes and imperfect fungus are caused all has effect preferably.Because long-term single use, preventive effect is on a declining curve but in recent years.
Polyoxin is a kind of New-type wide-spectrum antibiotics bactericide, has the interior preferably conduction of inhaling.Its mechanism of action is to disturb the chitinous biosynthesis of germ cell wall.Germ tube is with after mycelia contacts medicament, and cell inclusion is expanded, breaks, overflowed in the part, and can not normal development, causes death.Polyoxin also has the effect that germ produces spore and scab expansion that suppresses.Polyoxin in the Asia, regional extensive uses such as Europe, the Middle East, good to multiple fungal disease preventive effect, recommend under the consumption pesticide resistance phenomenon not to take place in routine, be a kind of rare outstanding biological bactericide.
Long-term practical application shows that polyoxin is to preventive effect ideals such as multiple main disease such as alternaria leaf spot of apple, apple mildew, ring rot of apple on the apple, but use cost is higher separately, is unfavorable for that large tracts of land promotes the use of; The carbendazim fungicidal spectrum is wide, and use cost is lower, but in recent years because resistance rises to some extent, uses preventive effect undesirable separately.The two is carried out compatibility, see theoretically, comprehensively their advantage is covered the shortage, and plays the effect that improves preventive effect, enlarges fungicidal spectrum, reduces cost.Field and indoor biometrics show that the two compatibility has synergistic effect preferably, and be single with being significantly improved than the two to the preventive effect of ring rot of apple.
