Description
The invention relates to a kind of bactericide of preventing and treating vegetables, fruit diseases, more particularly, is about a kind of composite bactericide of preventing and treating ring rot of apple, scab, cucurbits fusarium wilt and preparation method thereof.
By the pear scab of germ initiation, the ring spot of apple tree etc. all is that fruit tree is threatened bigger disease, domestic existing bactericide agricultural chemicals control efficiency is all not obvious, as the topsin carbendazim, though use cost is lower, but produced stronger pesticide resistance through long-term use for many years, the Japanese iprodione of introducing of many now employings, fast Poly etc., but because control cost height (price is up to 160,000 yuan/ton), use multiple low (500～800 times) effect also undesirable, and make the peasant be difficult to accept.
Scab of cucumber (cladosporium cucumerinum) is called cucumber shot hole (scab) in the past, is a kind of serious epidemic disease of cucumber.Do not report in the past in 1984 in China, proposed this name of disease of scab of cucumber first in " the protection ground vegetables extermination of disease and insect pest " of " Beijing agricultural science " editorial office publication in 1984.Method pure going up with " new disease-scab of cucumber " in " Liaoning agricultural science " in room reported in 1985, and described the pathogen form.
All organs beyond the scab of cucumber germ infringement cucumber root.At first occur elliptical spot when cotyledon is injured, enlarge gradually thereafter, even cotyledon rots; Occur the having one's hair waved shape when true leaf is injured earlier and present the yellow green spot, make scab flavescence brown again and dry and cracked perforation; Base portion is injured and bar shaped or oval patch are occurred, splits thereafter, usually fractures; Usually rot when terminal bud is injured, cucumber plant can not be grown, cause total crop failure; Flow out jelly after fruit (sugar-preserved gourd) is injured, cave in thereafter, sugar-preserved gourd distorted deformation and scab are innumerable, can not eat.
Scab of cucumber is distributed in Europe, America (U.S., Canada) (Soviet Union, France, Britain, Poland), Asia (Japan, Korea, India) abroad.Provinces such as domestic distribution Liaoning, Jilin, Heilungkiang, Shandong, Hebei and Inner Mongol, but attach most importance to Liaoning, Jilin, the Three Eastern Provinces, mountain.There are 46 counties, 12 cities that this disease takes place in Liaoning Province.The general time cucumber rate of being injured is 60%～70%, and severe patient reaches more than 90%, even total crop failure fully.Liaoning Province's injured area is more than 30,000 mu, and annual economic loss is more than 5,000 ten thousand yuan.
Scab of cucumber year of causing harm at home is not long, and to its control report seldom, the material of research scab of cucumber only proposes some and prevents and treats suggestion routinely, and points out its effectively preventing is awaited further research.Fang Fachun etc. point out in 1985 annual report roads: medicament can be tried out 50% benzene Lay special 1000 times of liquid, 500～800 times of liquid of 50% carbendazim, 600～800 times of liquid of 75% tpn or 400～500 times of liquid of 30%DT bactericide.Yuan Meili etc. (1986) report: 50% carbendazim has certain effect for 500 times, but undesirable.
In the control scab of the domestic present use medicament commonly used, the clear drug effect of sterilizing is very poor, and poisoning appears in mancozeb improper use meeting, and carbendazim, thiophanate methyl use year after year and serious pesticide resistance can occur, and the cucumber producing region in many areas is stopped using,
