After the fall of fruit trees, many fruit farmers do not know the hiding place of various diseases and insect pests in apple orchards, in fact, there are fixed wintering places, wintering places are more concentrated, and the implementation of effective prevention and control measures in winter is a favorable time. The following is introduced to the fruit farmer friends in combination with the actual production of the orchard, for the fruit farmer friends to implement in their own orchards.
Those who overwinter with mycelium, conidia or ascomycete shells have rot, dry rot, rot disease, rot disease, and black star disease, and those who overwinter with sclerotia have flower rot.
Those who overwinter with mycelium are anthrax, brown rot, penicillium, and black rot, and flower rot that overwinters with sclerotia.
Mycelium overwinters with mycelium in mold heart disease, powdery mildew, black star disease, anthrax, and gray spot disease that overwinters as conidia.
Those who overwinter with mycelium or conidia are brown spot disease, gray spot disease, rotiform disease, round spot disease, and spotted leaf litter disease, and ascosis that overwinter with ascomycete shells.
Those who overwinter with mycelium in the roots or remnants of diseased trees are round-spotted root rot, white-veined feather disease, and purple-veined feather disease, and those who overwinter with sclerotia are white silk disease, white-veined feather disease, and purple-veined feather disease.
Those who overwinter with eggs are warty aphids, and those who overwinter with larvae are the top-tip leaf curling moth and the white leaf curling moth.
Those who overwinter with eggs are apple red spiders, yellow aphids and sky curtain caterpillars, and those that overwinter with larvae or mature larvae are pear roundworms, bulbous insects, tea-winged bugs, apple-winged pyrifos, yellow thorn moths, and apple sword moths that overwinter with pupae.
Overwintering with eggs are the large green leafhopper, the macular leafhopper, the apple cotton aphid, and the Kang's mealybug. Larvae and old mature larvae overwinter with peach small heartworm, apple leaf curl moth, brown leaf curl moth, apple transfiguration moth, star caterpillar, mulberry cow, star cow, apple gidding worm, apple small heartworm. The whirling leafminer moth that overwinters with pupae, the hawthorn red spider that overwinters as adults, the pear blossom web bug, and the Kang's whitefly.
Grasshoppers that overwinter with eggs, and apple aphids, aphids, aphids, aeropheres, scarab beetles, scarab beetles, peach heartworms, and green thorn moths that overwinter with larvae or old mature insects. Pupae overwinter by spring inchworms, boat-shaped caterpillars, pear blossom web bugs, and adults overwinter with apple-haired scarab beetles, black-velvet scarab beetles, small blue-and-white scarab beetles, and hawthorn red spiders.
The above is the hiding place of the overwintering diseases and insect pests of the apple orchard, only by seizing the favorable opportunity of winter, taking effective control methods, the fruit trees use stone sulfur compound to clear the garden once before the leaves fall, and then clear the garden once before the budding of the fruit trees in the second year, which can reduce the base of diseases and insect pests throughout the year, and create favorable conditions for the orchard to produce abundant and stable yields and produce high-quality fruits. Understand the hiding place of diseases and insect pests, in order to know the occurrence of diseases and insect pests in apple production, the use of agronomic measures, biological control, physical and chemical agents integrated control, do not worry about the orchard can not produce high-quality fruit.
