The diseases of pomegranate mainly include dry rot, brown spot and hemp skin, which can seriously affect the quality of the fruit.
1. Dry rot: This disease not only invades the flowers and fruits during the growth period, but also invades the fruits stored. Control methods: 1 In the late autumn, early winter and early spring, timely cut off the dead fruit on the tree, the dried diseased branches, and burned intensively to reduce the source of the disease. 2 Before the onset of flowering, before flowering and after flowering, spray 1:1.5:160 Bordeaux mixture once, or spray 50% methyl thiophanate-methyl WP 800-1000 times solution, or 50% anti-hypertensive WP Powder 600 times solution. 3 At the same time as spraying and controlling, it is necessary to remove the diseased flowers and diseased fruits in time.
2. Hemp disease: It is caused by a variety of fungal infections, which causes the skin to become numb. The prevention and treatment of this disease has a good effect with 25% gram of EC. Its active ingredient is difenoconazole. Because it is an emulsion, it has better penetration, adsorption and conduction effects, and it is resistant to rain and has a long lasting effect.
