Description
Technical field
The invention belongs in the agricultural production fruits and vegetables technical field of preventing and curing diseases, be specifically related to a kind of plant resource biocide preparation and the application in the control pepper anthracnose thereof.
Background technology
Pepper anthracnose (Colletotrichum capsici) is that the speciogenesis on capsicum, the pimento is general and endanger serious worldwide disease.In recent years, along with the continuous expansion of pepper planting area, the disease of capsicum trend multiple and that increase the weight of is obvious day by day, and therefore the yield and quality of capsicum receives very big influence.Pepper anthracnose is the regular incidence evil on capsicum produces, and it is general to distribute, especially in the rainy time; Main harm fruit and blade are the main causes that causes capsicum " three fall ", and diseased fruit rate is about 10% usually; Diseased fruit rate reaches 30%～40% when serious, but the underproduction can cause that pepper seedling is dead more than 50%; Leaf really rots, and is all influential to capsicum quality, output.Pepper anthracnose is several kinds of caused fungal diseases in the Deuteromycotina colletotrichum (Colletotrichum Cord).Pepper anthracnose can cause harm Folium Capsici sheet and fruit show the circular spot of water soaking mode brown, verticillate pore on the scab on sick leaf; Sick fruit goes up and is the circular spot of water soaking mode brown, and scab is protruding gradually, forms taupe, black or orange red granule point, is arranged in the concentric wheel stripe spot, and pale red or orange red mucilage are often overflowed in disease portion during high humidity, i.e. conidium.The drying shrinkage attenuation of disease portion is prone to break when dry.Pepper anthracnose can be divided into red anthrax bacteria, black anthracnose bacterium and stain anthrax bacteria according to the disease symptom.
Present on the means of control pepper anthracnose, mainly still chemical control, chemical control is to use bactericide to prevent and treat pepper anthracnose.Efficient, quick-acting, easy to use, economic benefit advantages of higher that bactericide has, but have only protective effect, do not have treatment and root out effect, and the lasting period to be short, application times is many, and germ has produced pesticide resistance to it; Long-time unreasonable use chemical pesticide control pepper anthracnose causes pathogen to develop immunity to drugs gradually, and control efficiency reduces, and can increase residue of pesticide in the fruit, and contaminated environment increases production cost.Chemical pesticide still is difficult to solve effectively to people and animals' toxic and side effect and residue problem so far.
Along with improve constantly with various countries the pay attention to day by day to protection environment for human survival of the world today to crops quality and quantity demand; And the deepening continuously of sustainable agriculture and lasting plant protection idea; The production of people's growing interest environmental problem and pollution-free food; Developing out efficient, environmentally friendly botanical biological pesticide control pepper anthracnose is the focus of studying at present, also is developing tendency in future.Through the biopesticide of processing after the improvement of vegetable source natural compound, not only control efficiency is good, also to fruit, flower, the Ye Douwu harm of plant, to the person poultry safety, has efficient noresidue, no poisoning, advantages such as the non-resistant property of medicine; In the control disease, can effectively improve quality of agricultural product simultaneously.
Summary of the invention
