Pest and disease control of yellow peel

Pest Control

The kumquat fruit is extremely susceptible to diseases and pests during the ripening period. The common diseases include soot and anthrax; the pests include aphids, moths, scale insects, etc. The main measures taken are generally a combination of physical, chemical, biological and other methods.

aphid

Aphids are insect pests that lay eggs densely attached to the stems and leaves of plants. A large number of larvae eat the leaves and fruits, causing serious impact on the fruit production and quality of kumquats. General prevention and control can be achieved by cleaning and pruning diseased and insect-infested branches after the fruits mature in autumn, and burning the insect eggs to prevent them from harming the health of the plants again in the next year. In addition, pesticides can be sprayed together, and the effect of chlorpyrifos emulsifiable concentrate is very good.

Disease control

anthrax

Not only kumquat trees, many fruit trees and flowers will be affected by anthracnose. The yellow peel is at risk of anthrax throughout its growing period, especially from June to October each year. The control method is to promptly handle drainage after heavy rain, prevent aquatic bacteria from infecting plants, do a good job of sanitation and cleaning of gardens or potted plants, prune diseased branches and leaves, and clean up rotten fruits. The chemical method is to use pesticides by mixing thiophanate-methyl, thiophanate-methyl, benomyl and other drugs in a certain proportion and spraying them.
