Pest Control Method of Fruit Trees

(  Rate Of Fluvoic Acid )

Symptom identification

The main harm of the apple tree trunk, branches and main branches, branchlets at the cortex. Leading to cortical rot and necrosis. Symptom divided disease type and branch type. "Canker" at the early stage of the disease, disease of red brown, hygrophanous, soft tissue, squash with the hand can be brown juice outflow, cortex decay, lees flavour. Dry shrinkage in the late lesion, dark brown, warty surface appears black small, when the weather is wet, yellow filaments drop out. "Dieback" symptoms were more common in 2 ~ 4 years old a small piece of paper, fruit, such as fetal position, lesion shape irregular, expansion speed, quickly around the branch a week, caused shoot dieback.

Prevention and cure method

First, to strengthen the cultivation and management, rational pruning, fertilization and watering to prevent early deciduous, frost damage and protect wound, enhance vigor. In the spring of second, curettage of lesion, disinfection and treatment of disease, collocation using Huminrich, can enhance the disease resistance. Third, bridge and foot connected to the larger part of disease, improve nutrient transport, restore growth. Fourth, stem white, before winter and early spring to stem white, can reduce the temperature of the bark, prevention of frost damage. Fifth, pay attention to the orchard health, sick body died branches and scraped out in the orchard.

(Two) Pear Black Spot (Pear Dry Wet Rot)

Symptom identification

The main damage leaves, fruit and leaves slightly, infection occurred in the leaves on the important. Young onset generated when the size of a pinhead, round, brown to black brown spots, margin distinctly, after lesion gradually expanded was nearly round or irregular spots, central gray white to gray brown, sometimes lesions have round lines, when wet, the lesion surface produces a large number of black mold layer, young victims, in the fruit surface produced one or several Brown circular needles, gradually expand the size of the spots, is near circular to oval, brown to black brown spots slightly concave, wet on surface of black mold layer. With the fruit growth, fruit cracking, cracks can be as deep as the core, the inner crack produce black mold, fruit disease caducous, grown fruit damage, lesion larger, dark brown, late fruit softening, corruption and fruit drop, slightly and diseased petioles, early lesion for black oval, slightly sunken. After the expansion of long oval, pale brown, significantly depressed lesion, junction of disease and health often cracks

Prevention and cure method

First, clear the source of bacteria with pruning, complete removal of orchard leaves, fruit, cut off sick shoots, in order to reduce the source of bacteria. Second, rational distribution of varieties of local conditions to plant quality and disease resistant varieties, pay attention to the rational distribution of varieties. Third, enhance plant disease resistance with the use of Huminrich of organic fertilizer to increase its resistance, rational pruning, in order to facilitate ventilation and light, the timely removal of weeds, prevent good other plant diseases and insect pests, the low-lying or poor drainage of the orchard, should improve the drainage ditch industry and trade. Fourth, fruit bagging to protect the fruit from disease infection.

(Three) Apple Mould Rot (Brown Heart Disease, Mold Heart Disease)

Prevention and cure method

First, clean the orchard. Autumn and winter to remove diseased fruit, leaves, tree branches cut off dead fruit, burned. Second, early spring bud collocation moderate HUMINRICH organic fertilizer or liquid fertilizer, enhance disease resistance, increase the organic matter content in the soil, improve the capacity of water storage and water storage. Fourth, to strengthen the management of fertilizer, rational pruning, improve tree light and ventilation conditions, cultivation of high pile fruit. Spraying moisturizing agent, artificially closed calyx tube and preventing the bacteria infection and morbidity.
