Reasons for prevention and treatment of kiwifruit pests and diseases in winter: the pathogens in winter are in dormant period, parasitic among diseased branches, deciduous and rotten fruits. They can be combined with winter shears to remove diseased branches, insect branches, fallen leaves and fallen fruits in the garden for deep burial. Or incinerate. This can effectively eliminate pathogens such as ulcer disease, leaf blight, and black spot disease, and reduce the source of infection.
Common pests and diseases in winter: Mainly pay attention to the winter prevention process: root rot, root knot nematode, scale insect, leafhopper, and cockroach pests, which are the most common diseases and insect pests of winter kiwifruit. Everyone explains their respective prevention methods.
In the prevention and treatment of kiwifruit ulcer disease, the kiwifruit garden with severe ulcer disease is combined with the winter shearing garden, and the spraying of sulphur sulphur mixture of 0.3 to 0.5 Baume is carried out 1 to 2 times, and the Bordeaux mixture of 1:1:100 is added. Prevention and treatment.
Prevention and control of root rot can be combined with deep-turning to treat soil chemicals and eliminate underground larvae and mites. Pesticide manufacturers recommend using 3% carbofuran for 3 to 5 kg per acre for soil treatment, which can eliminate root-knot nematodes, eliminate underground pests, reduce the wintering base of pests, and greatly reduce the harm in the coming year.
The kiwifruit scale insects are mostly overwintered on the trunks and branches of the trees. In winter, rags, straws, bamboo brushes and other tools can be used to wipe the dense wintering insects and reduce the insects in the coming year. The insect branches on the branches can be removed in combination with winter shears.
Kiwi, leaf mites, and mites, such pests, in winter and adult weeds in weeds and dead leaves, can be combined with clear gardens and eradicated weeds to concentrate or burn, to eliminate wintering adults and eggs.
The control of kiwi root-knot nematodes can be combined with deep-rooting before winter, excavating the diseased roots and fine roots of 5-15 cm of the topsoil of the diseased plants, removing the diseased bodies, reducing the source of the disease and reducing the harm.
In winter, the common pests and diseases are the above. It is necessary to strengthen management and timely discover and timely use drugs for prevention and treatment. China Pesticide Network reminds everyone to spray pesticides in moderation to avoid phytotoxicity.
