Embodiment

[0008] When the grapes just set fruit, spray the grape fruit and plants with a mixed solution of 25% azoxystrobin suspending agent 1500 times liquid and 20% difenoconazole water dispersible granule 3000 times liquid.

[0009] When the young fruit expands and develops, use 600~800 times of 70% mancozeb wettable powder to spray the grape fruit and plants.

[0010] Before the fruit is sealed, the grape fruit and plants are sprayed with a mixed solution of 50% thiram wettable powder 1500 times liquid and 40% flusilazole EC 8000 times liquid.

[0011] After grape thinning and before bagging, use a mixed solution of 25% azoxystrobin suspending agent 1500 times liquid and 20% difenoconazole water dispersible granule 2000 times liquid to spray grape fruits and plants, and use the same Concentrated medicinal solution dipped in fruit ears.

[0012] Grasp the timing of spraying: the spraying operation should be carried out according to the above timing. In case of cloudy and rainy weat...

Abstract

The invention discloses a method for preventing and controlling anthracnose of grape, belonging to the field of fruit tree disease prevention management. The method comprises the following steps of: at the beginning of fruit setting of grape, spraying the mixed solution of azoxystrobin and difenoconazole; spraying mancozeb when young fruits expand and grow up; before spike sealing of the fruits, spraying the mixed solution of thiram and flusilazole; and spraying the mixed solution of azoxystrobin and difenoconazole after fruit thinning of grape and before bagging, and dipping fruit spike in the mixed solution with the same concentration. According to the method, anthracnose of grape is prevented and controlled in four stages, namely the stage of fruit setting of grape, the young fruit expansion state, the stage before spike sealing and the bagging stage, and corresponding pesticides are applied in different stages for preventing and controlling anthracnose of grape; therefore, the incidence of anthracnose of grape is controlled effectively, and the yield reduction of grape caused by anthracnose is controlled to be within 5%.

Description

technical field [0001] The invention relates to a disease prevention method for fruit trees, in particular to a method for preventing and controlling grape anthracnose. Background technique [0002] Anthracnose is caused by Deuteromycotina, Anthrax genus Gleospora anthracnose ( Colletotrichum gloeosporioides Penz) infection. The disease is serious in rainy and high humidity seasons. If the management is extensive, the orchard is not cleaned thoroughly, the amount of branches left is too large, the ventilation and light transmission are poor, and the field microclimate has high humidity, the disease will also be serious. For a long time, anthracnose has been the most troublesome disease for grape growers. Grape orchards are affected by grape anthracnose, and the yield reduction is generally 20-35%, and more than 90% in severe cases. Although there are many kinds of pesticides with different effects, and the disease can be effectively controlled by bagging technology, ther...
