Olive tree pest control mainly adopts chemical control, that is, by spraying insecticides. They are more likely to produce wood lice and bee shell insects during the growth period, which can be prevented by spraying 1000 times of water amithion solution on the leaf surface. In addition, there are some other green pesticides with good insecticidal effect, which can also be used. However, when spraying, we must pay attention to controlling the concentration and amount of pesticide, and do not spray too much, so as not to hurt the olive tree. 1、 How do olives prevent insects? The pests that are easy to appear in the process of olive growth are wood lice and bee shell insects. When these two pests occur, they will directly eat leaves and affect the normal growth of branches and leaves. The prevention of wood lice can be sprayed with 1500 times monocrotophos solution or 1000 times Isocarbophos solution. Bee shell insects can be sprayed with 700 times of quick killing emulsion, or with a mixture of Omethoate and 1000 times of parathion. Both pesticides can be sprayed directly on the upper and lower parts of the leaf surface, which has a quick effect and good effect. 2、 How to fertilize olive trees 1. Fertilizing young trees: when olive trees are in their infancy, they need a lot of fertilizer in all aspects of their growth, and their roots are not perfect, so they need a lot of nitrogen fertilizer. It is suggested that topdressing should be carried out once a month, mainly with nitrogen fertilizer and supplemented with other compound fertilizers. This can promote the growth of their rhizomes and improve their disease resistance.
2. Fertilization for mature trees: fertilization for mature trees is mainly to improve the flowering and fruiting rate and improve the quality and yield of fruits. Before fruit bearing, more phosphorus and potassium fertilizer can be applied to expand the fruit. After the results, apply more nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer to supplement the nutrients in the soil. Attention should be paid to trenching and fertilization during fertilization, so that the roots can naturally absorb nutrients and avoid burning the roots. （GanLanZenMeFangChong）
