Background technology
Wheat paddock is one of generalized grain crop of China four, and many factors such as climate influence, the hair of wheat paddock head blight
Life aggravates year by year, turns into an important factor for restricting wheat paddock yield and food security.Wheat scab is called that the wheat head is withered, rotten wheat
Head, red wheat head, it is one of disease more serious in one of Major Diseases of wheat, and wheat earing stage " three sick three worms ".It is small
Wheat head blight generally occurs in the whole world, is distributed mainly on moist and half tide wet zone, especially weather with moistening rainy temperate zone
Area is aggrieved serious.Circulate a notice of according to relevant department, 2012, Huang-Huai-Hai farming region province wheat scab occurring area is about 24,600,000
Mu, accounted for the 68.3% of the whole province's wheat planting area, created the pathogenetic history of province's gibberella saubinetii most, though through with all strength
More than 20 hundred million jin of yield is retrieved in preventing and treating, but still makes wheat yield cause necessarily to lose, and is had peasant household therefore is caused to have no harvest, suffers great
Loss, wheat scab turn into the major hidden danger for influenceing Quality Wheat high yield, should cause everybody great attention.
Wheat infection head blight influences whether yield and quality of wheat, if preventing and treating is improper to cause wheat yield, seriously
Meeting cause to have no harvest.There is media report, just there is within 2012 peasant household to infect head blight (really by immature in Anhui Province somewhere
Recognize and had no harvest) wheat ahead of time gather in, stalk is sold to dairy cow farm to feed ox with the price of 0.15 yuan/jin, it is such
Wheat straw is verdant healthy and strong but the wheat head is withered turns white.Meanwhile quality reduces after wheat infection head blight, seed is shrivelled,
Flour extraction reduces.Wheat scab not only causes serious production loss and qualitative effects to Wheat Production, it is often more important that its disease
Wheat toxin influences food security, enjoys multi-party concern.Head blight is caused by fusarium fungus, causes to damage in the yield to wheat
While mistake, also produce the mycotoxin based on deoxynivalenol (i.e. vomitoxin DON), have to people and animals compared with
Big harm, the acute poisoning symptom such as dizziness, fever, nausea, diarrhoea can be caused by eating sick wheat, can be caused bleeding when serious, shadow
Immunity and fertility etc. are rung, directly human and livestock health and life security are constituted a threat to.Therefore, sick wheat rate content reaches in wheat
It can not be eaten when more than 4%, while illustrate that wheat has lost commodity value, need to separately dealt with.In 2012, there is media report
In A Certain Locality, Jiangsu Province is because wheat infection head blight, staple food control office reject wheat.In a word, or without yield after wheat infection head blight,
It is to have had yield but wheat can not be sold, without income.In view of the serious harm of head blight, has caused the height of peasant household
Degree is paid attention to, and takes a series of measures, and according to reflection, prevention effect difference is larger.Find peasant household to head blight by inquiry
Understanding is still inadequate, prevents and treats in head blight and still suffers from many mistaken ideas.
