Description
The invention relates to a kind of control vegetables, the bactericide of melon and fruit disease more particularly, is about a kind of composite bactericide of preventing and treating anthracnose and preparation method thereof.
Cucumber anthracnose (colletotrichum Lagenarium) is a kind of serious popular destructive disease of cucumber.Seldom reported in China that the control of cucumber anthracnose was strengthened in serious first proposition in " the protection ground vegetables extermination of disease and insect pest " of " Beijing agricultural science " editorial office publication in 1984 in 1984 in the past.Method pure going up with " new disease-anthracnose of cucumber " in " Liaoning agricultural science " in room reported in 1985, and described the pathogen form.
All organs beyond the cucumber anthracnose 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.
Cucumber anthracnose is distributed in Europe, America (U.S., Canada) (Russia, France, Britain, Poland), Asia (Japan, Korea, India) abroad.Provinces such as domestic distribution Liaoning, Jilin, Heilungkiang, Shandong, Shanxi, Hebei, Henan, Inner Mongol, Anhui, Jiangsu, Zhejiang, but attach most importance to Liaoning, Jilin, Shandong, Hebei.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 100%, have in addition 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.
Cucumber anthracnose year of causing harm at home is not long, and to its control report seldom, the material of research cucumber anthracnose 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 all undesirable, can not control the big generation of disease.
The anthracnose that cucumber, watermelon anthrax bacteria cause, it is very big in the melon production area of China area to take place, and seriously takes place year by year, to melon quality and yield influence greatly.Old medicines such as tpn commonly used at present are owing to use pesticide resistance extremely strong throughout the year, also has the U.S. old medicine of 80% anthrax good fortune because proportioning is unreasonable, effect is not high, annually on producing to spray repeatedly the big generation that agricultural chemicals is not controlled disease yet, therefore, melon production dosage increases, and effect is undesirable, and many areas are stopped using.
