How to control longhorn beetle larvae? Detailed explanation of control methods and technical key points
How to control longhorn beetle larvae? Longhorn beetle larvae cause very severe damage to fruit trees. How should they be controlled? Please provide methods. Damage caused by longhorn beetles: larvae of the bark-girdling longhorn beetle girdle the bark (gnawing the green surface layer of the trunk); larvae of the Miezi ridge tiger longhorn beetle damage branches and trunks, boring the xylem into crisscrossing tunnels and boring toward the center of the stem, damaging the pith, then boring downward to damage the roots. This seriously affects water transport, causing weakened tree growth, withered yellow branches and leaves, and symptoms of fertilizer and water deficiency.

Three key points for good herbicide efficacy to remember
1. Pay attention to applying the herbicide before the seedlings emerge as much as possible. Chemical weeding in vegetable fields mostly uses soil treatment, but it must be applied before sowing or before emergence after sowing, and the best time to apply it is at the initial stage of weed growth. This can avoid or reduce contamination of vegetables by the chemical. 2. Pay attention to making the soil level, fine and moist. When using...

What are the key points of knowledge about mixing pesticides?
In recent years, vegetable nematode disease has become an important type of disease in vegetable production, especially in protected vegetable production. It occurs rather commonly, causes relatively severe damage, and is also relatively difficult to control. For the control of vegetable nematode disease, in addition to some conventional agricultural control measures (such as selecting resistant and tolerant varieties, cultivating disease-free seedlings, rational...

How to use herbicides in vegetable fields safely? Master these key application points
Weeds in vegetable fields are a major problem in vegetable production. Hand weeding is both labor-intensive and backbreaking, so the vast number of vegetable growers need to use herbicides in vegetable production. However, vegetables come in many varieties, have short growing periods, high multiple-cropping indexes, and complex crop rotations, and there are also many types of herbicides. If used improperly, they can easily cause herbicide damage, or even total crop loss...
