How does Noni fruit prevent insects

Artificial trapping and chemical spraying are two main methods of controlling pests in Noni fruit. Artificial trapping can effectively reduce the number of adults and reduce the birth rate of larvae. Because traps can be made by hand, artificial trapping is a low-cost pest control method. Spraying chemicals is a way to use the toxicity of chemicals to kill pests. Therefore, in the process of spraying chemicals, attention should be paid to prevent harmful substances from remaining on the fruit. 1、 How to prevent insects in Noni fruit 1. Artificial trapping: traps such as yellow board and black light can be used to trap and kill pests. Because pests have a certain phototaxis and colortaxis, arranging a certain number of traps in orchards can achieve a good effect of preventing pests. In order to maintain the effect of trapping and killing, the trap should be cleaned or replaced every week.

2. Spraying chemicals: chemicals play a great role in the prevention and control of pests. Because it is a substance that can kill pests in a large area and with high efficiency. But it also has some disadvantages, it is easy to leave harmful substances on Noni fruit. Therefore, when spraying chemicals, we must find and treat them early, and spray the least amount of chemicals within the minimum range to control pests. 2、 How to plant Noni fruit 1. Seed reproduction: clean the fully mature seeds, disinfect them, enhance their resistance to the virus, soak them in warm water for 24 hours, wrap the seeds with wet gauze and place them in a warm environment for germination. After the seeds are exposed, they can be evenly sown in the soil for seedling raising.

2. Cutting propagation: the cutting propagation of Noni fruit is best carried out from March to April every year. Select the branches of Noni fruit in good growth condition without diseases and pests as cuttings, and cut the branch mouth into an inclined plane. In order to the survival rate of branches and prevent the occurrence of diseases, cuttings need to be disinfected before cutting. (NuoLiGuoZenMeFangChong)
