Abstract
The invention relates to a crop gray mold prevention and treatment agent, which takes an extract of a leaf of cattail as a raw material. The extract comprises a preservative. According to the agent, the leaf of the cattail is taken as the raw material; the extract can be obtained by decocting or juicing, then is sprayed onto crops after diluted with water, and can exert a prevention function when the crops are not attacked, and exert a good treatment function when the crops are attacked; a cure rate reaches 100% according to a field test; the agent not only can prevent and treat gray mold, but also has an obvious preventive effect on other fungus diseases; and in addition, the leaf of the cattail is a wild vegetable, and can be eaten, so that the problem of pesticide residue cannot occur in actual use.
Description
Technical field
The invention belongs to
crop gray mold Prevention Technique field, especially a kind of crop gray mold control medicament and preparation method thereof.
Background technology
Gray mold is a kind of fungal disease of the common and more difficult control of open country, protection ground crop; belong to low temperature and high relative humidity type disease; mainly caused by Botrytis cinerea, it is the high-incidence season when above that this pathogen continues 90% in 20～30 DEG C of temperature, humidity, can encroach on flower, really, leaf, stem etc.When Chinese olive is injured, residual column cap or petal are many first to be infected, and backward fruit expansion, causes pericarp to be canescence, and has the mould layer of thick grey; In blade when morbidity, is from blade tip, along inwardly expansion between vein.When this disease occurs, if control not in time, can cause the large area of crop to catch an illness, cause the underproduction, finally cause the serious economic loss at plantation family.
People are in order to prevent gray mold, the multipath integrated control that general employing is made up of cultural control, chemical control and biological control, comprise: cultural control comprises the methods such as seed sterilizing, empty canopy sterilizing, rational close planting, clean rural area, chemical control comprises that medicines such as using phonetic mould amine, procymidone tmtd sprays, and biological control comprises that a gram trichoderma harzianum, organosilicon etc. spray.
In above-mentioned three kinds of modes, cultural control belongs to complementary method, the route of transmission of the isolated pathogen of its main purpose, Initiative defence is mainly carried out in chemical control in the time of morbidity, biological control belongs to the emerging method of preventing and treating, thus chemical control or the main method using, but use in a large number chemical agent, can cause the medicament residue in crop, and effect not fine.
