Key periods for applying pesticides to fruit trees
(Agricultural Wealth Network) In fruit tree cultivation, to increase fruit yield and quality, reduce the number of pesticide sprays, and extend the tree's growing life, the following key periods should be well managed for pest and disease control.
1. The period when buds are clearly swelling, that is, the bare-branch spray. At this stage, spray high-concentration fungicides plus insecticides, and spray thoroughly both on the tree and under the tree. It mainly controls various overwintering fungi and pests.
2. At the flower bud stage, spray higher-concentration fungicides plus insecticides, mainly to control flower rot, etc.
3. One week after petal fall, spray fungicides and insecticides, mainly to prevent various diseases and aphids, red spiders, pear psylla, etc.
4. After picking the fruit and before leaf fall, spray higher-concentration fungicides and insecticides, mainly to eliminate overwintering pests and diseases and reduce damage the following year. When mixing sprays, note that alkaline pesticides and slightly acidic pesticides must not be mixed.
