Prevention and control of powdery mildew For fruit trees with powdery mildew, at an angle of 15 cm from the plant, excavate an annular groove of 10-20 cm deep, apply 10-20 kg of grass ash in the ditch, cover with a layer of thin soil, and control the white powder of the fruit tree. The disease effect is better.
To prevent root rot, first open the soil of the root of the fruit tree, remove the soil around the root of the rot, scrape off the root bark of the disease, and after drying for 24 hours, each plant is covered with 3-5 kg ​​of fresh grass ash, and then covered with soil to control the root rot of the fruit tree. good results.
Prevention and control of rust fruit disease For the apple tree that has already been diseased, an annular groove with a width of 50 cm and a depth of 60 cm is excavated at a distance of about 50 cm from the root, and then the grass ash is used as a base fertilizer into the ditch, and the water is poured and pressurized. New soil can be.
Prevention and control of blight and anthracnose In the diseased seedling stage, the planting of ash is carried out along the ridge, and the dosage of 30-50 kg per mu can effectively prevent the occurrence of these two diseases.
Prevention and treatment of early defoliation disease 8 kg of grass ash water 100 kg, soaked for 48 hours to filter, the filtrate and fungicide mixed spray, has a certain prevention and treatment of apple early defoliation, the effect is better than single spray bactericide.
Prevention and control of mites With 10 kg of grass ash and 50 kg of water, soaking for 48 hours to filter, taking the filtrate to spray, can effectively control the mites on the fruit trees.
