Fruit Root Disease Control Measures

In the process of fruit tree cultivation, people pay more attention to the prevention and control of pests and diseases such as trunks, branches and leaves, and often use pesticides and other control measures. The prevention and treatment of root diseases of fruit trees is often overlooked, thus seriously affecting the yield and longevity of fruit trees. The roots of fruit trees suffer from many diseases. To obtain high yields of fruit trees and prolong the life of fruit trees, we must pay attention to the prevention and treatment of root diseases of fruit trees. 1. The root rot of round spot mainly harms fruit trees such as pome fruits, stone fruits and walnuts. Diseased leaves, clusters, wilting, curling, dehydration and dryness of leaves, reddish-brown halo with main veins spreading, branches dry, cortical necrosis easy to peel; fibrous roots turn brown and dead, the roots of the roots are red-brown round spots, deep into xylem, Roots blackened and died. 2, root rot damage pear, apple, hawthorn, apricot and so on. Partial or whole plant leaves are small and thin, yellowing off. The new shoots are short and the fruit is small; the roots are immersed in purple and ulcerated, with white fan-like mycelium between the cortex and xylem, a mushroom flavor, and fluorescence. 3. The orchards of beach with white sand, heavy soil, and poor drainage are prone to occur. Pome fruits, stone fruits, grapes, oranges and wild jujube all occur. The site of the disease was root and neck, brown spots with watery leaching, long white mycelia, diseased parts and long brown sclerotia in surface cracks. 4, white feather disease endanger a variety of fruit trees. Invasive fine roots first, and then extended to lateral roots, main roots. On the surface of the diseased roots, white or gray-white reticular mycelia or rhiform mycelia were present, and round black sclerotia were produced in the decayed xylem. 5. Poorly drained viscous soils with physiological rot. The orchards with excessive salt content, too high groundwater level, or drought and water shortage are susceptible to disease. The long-term water in the roots, the roots without root hair, and the cortex rot; the main roots are dry and dead, and the leaf margins are charred and yellow. 6. Control measures 6.1 Increase organic fertilizer or application of antibiotic fertilizer and cake fertilizer to increase tree vigor. 6.2 discharge water. 6.3. Remove mycorrhizal, sterilize roots and replace with sterile new soil. 6.4 Sterilize pentachlorophenol sodium 250--300 times; 70% thiophanate-methyl 1000-times; 50% Benzoate 1000--2000-times; 70% pentachloronitrobenzene per plant. 50--100 grams of liquid medicine, 150--300 grams of medicinal liquid per tree, mixed with new soil applied to the roots.

Millets are a group of highly variable small-seeded grasses, widely grown around the world as cereal crops or grains for fodder and human food. Millets are important crops in the semiarid tropics of Asia and Africa (especially in India, Mali, Nigeria, and Niger), with 97% of millet production in developing countries. The crop is favored due to its productivity and short growing season under dry, high-temperature conditions. In a 100 gram serving, raw millet provides 378 calories and is a rich source (20% or more of the Daily Value, DV) of protein, dietary fiber, several B vitamins and numerous dietary minerals, especially manganese at 76% DV (USDA nutrient table). Raw millet is 9% water, 73% carbohydrates, 4% fat and 11% protein.
