Prevention agents: 20% leaf blight azole (Chunlei Wang Copper, in the raw fungus) 40 to 50 grams of 30 pounds of water into the head of the mango tree, according to the size of the tree increase or decrease in the agent, the small use of 40 grams, the large use of 50 grams. In the two canopy leaf period, flowering period, fruit growth period of these growth points were used in the beautiful fruit An spray, supplemental nutrients, increase the thickness of the leaf, fruit wax layer, increase the chlorophyll content, improve the mango's self-nutrition capacity, at the same time can play a role in preventing sunburn and other diseases.

Mainly caused by bacterial fungal deficiency of calcium and magnesium, in advance to do a good job of calcium and magnesium fertilizer supplementation and more lichen bacillus type fungicides can be prevented. Once produced, is the spraying of Dyson manganese zinc + amino acid type calcium and magnesium foliar fertilizer cabbage bacterial angular spot disease onset of the initial stage, the leaves produce oil stain-like spots, light brown to brown, gradually change to black brown, the spot into polygonal, the late leaf local rot with a peculiar smell. According to the survey, cabbage bacterial angular spot disease in cabbage seedlings 12 days (seedling stage) began to develop,.

Angle spot disease is also known as bacterial black spot disease or ulcer disease. The main damage to the tips, leaves and fruits. Not turn green new tips infected leaves now pinhead-sized small black spots, and then expanded to a small raised black spots, surrounded by a yellow halo, the spots were polygonal, late spot fusion into irregular large black spots at present conventional control of the use of chemicals, can only play a role in killing the bacteria on the surface of the tree, may be a few days after the use of drugs to see the disease is under control, but after the storm or typhoon, it will recur, fruit growers and friends have been spraying the drug! The cycle of curing the disease.

Bacterial hornblotch disease not only harms the leaves, but also seriously affects the fruit, you need to use the beautiful fruit An 100-150 times + garlic oil 1000 times + chemicals together, spray, 3-5 days once, the interval of adding chemicals. The effect is good, recently is also the last period of the prevention and control of bacterial hornblotch disease repair land, long-term use of chemical fertilizers, pesticides, the structure of the land acid-base balance has been destroyed, nutrients in the micronutrient plants can not be absorbed, the benefit of the bacteria to reduce. Biofungus can Jiang soil trace elements released, nitrogen fixation and carbon fixation and fruit trees to provide more and better nutrients.
