At present, chemical prevention and control is still an important means of kiwifruit pest control, especially when the pests and diseases are serious, chemical pesticides are an important means to effectively control pests and diseases. During the kiwi flowering period, the temperature began to rise, and the overwintering adults of pests such as Tsubaki elephant and Scarab began to be active, and the pathogenic bacteria of various diseases also began to infect and lurk at this time. Therefore, the kiwi flower period is the best period to control a variety of pests and diseases, and it is necessary to be cautious in the use of drugs, pay attention to the accurate selection of chemical pesticide varieties, the precise dosage used, the precise control period, and the precise control parts.
From mid to late April, it is in the kiwifruit season, which is also a critical period for the occurrence and control of pests and diseases such as kiwifruit bud maggots, thrips and gray mold.
For the prevention and control of flower buds and maggots, when the buds are white 5-10 days ago, the ground control is implemented, and when the top of the bud is white, the crown control is used. Ground prevention and control agents can be selected 3% phosphine granules 5-10 plants/1 kg, 0.5% clothianidin granules 6-8 plants/1 kg, 2% imidacloprid granules 10-15 plants/1 kg and other agents, evenly sprinkled around the canopy. For crown control, 6000-7000 times of 600g/L imidacloprid suspension, 3000-4000 times of 30% clothianidin suspension, 1000-1500 times of 5% lice and mite urea suspension can be selected.
For the prevention and control of thrips, when the flower buds are white, you can choose 60g/L ethyl spinosasad suspension 800-1500 times or 70% acetamiprid water dispersible granules 5000-6000 times for crown spraying.
For the prevention and control of gray mold, in the early flowering stage of kiwifruit, 50% iprodione suspension 1000-1500 times liquid and other agents can be selected for crown spraying.
