What are the common problems of fruit farmers in pest control? Why?

How to control pests and diseases in the process of fruit tree planting. Fruit farmers will find that their own fruit trees have serious pests, which are difficult to control, while neighboring fruit trees have relatively mild symptoms and are easy to control. What is the reason?

The above situation is mainly due to some problems in the process of prevention and control. The following little helper will explain it in detail for you.

Only attach importance to chemical control, ignoring agricultural control. Some fruit farmers, in the process of planting, think about insect treatment and disease treatment. In any case, if there are several pesticides and pests, they can always be dealt with, ignoring agricultural control. This method may be in a short time, but it is not sustainable. Once the time is too long, shortcomings will appear. Combined with agricultural control, the cost is low and the effect is good, such as pruning fruit trees, strengthening water and fertilizer management, not mixing with fruit trees, ploughing the soil in time and so on. , can be a good pest control. Farmers who overuse pesticides and use some fruits for pest control only consider pests and diseases, and do not consider other aspects. Therefore, their resistance to pests and diseases is getting stronger and stronger. With the passage of time, the cost has increased a lot, but the preventive effect is getting lower and lower.

In order to prevent and control pests and diseases, farmers who choose some fruits as pesticides use highly toxic pesticides unscientifically and rationally. The consequences of this will not only destroy the ecological environment, but also bring pesticide residues, which will become more and more difficult to control in the later stage. Not protecting natural enemies In terms of pests, although there are many insects on fruit trees, there are also many natural enemies. When controlling pests, using pesticides on a large scale will kill both pests and natural enemies, which will affect the ecological balance and is not conducive to long-term planting. Leaves, branches, rotten fruits and weeds in the orchard are not cleaned in time, which provides a place for the survival and reproduction of pests and diseases, and the number of pests and diseases increases, making the occurrence of pests and diseases more and more serious.
