Jujube pest control five attention

Understanding the role of pharmacy Each pesticide has a specific function. If the knowledge is vague, using the wrong pharmacy will not only cost money, but also delay the optimal prevention period and bring about adverse consequences. Take the killing drugs, the same is the killing drugs, but the period will be different. Many jujube farmers are confusing about killing eggs, killing nymphs or killing insects. For example, if you kill the winter eggs, you should use scorpion or net, and you should not use scorpion spirits or broomstick nets. Otherwise, the worms will be paralysed.

Pay attention to the harm of diseases and insects. Symptoms and initial and prosperous periods Since many juvenile farmers do not read or read newspapers at ordinary times, they do not know what kind of diseases and insect pests are caused by the symptoms of jujube trees, and they do not understand the occurrence of various pests. During the period of prosperous time, the use of spraying time and the type of medicine used became problems. If the jujube tree begins to sprout, the juvenile mosquitoes begin to appear. Their larvae suck the juice of the young leaves of the buds, causing the wounded leaves to grow vertically, and the affected parts turn green from red to green and hard and brittle until they wither. Some farmers cannot make accurate judgments.

After harvest, jujube fruit must also be prevented from being stopped by the majority of jujube farmers after harvesting of jujube fruit. This has laid down hidden dangers for the increase in the number of disease-infested bases for overwintering, leading to the proliferation of pests and diseases in the coming year.

It is necessary to pay attention to comprehensive prevention and control. At present, most jujube farmers still use chemical prevention and control, although the effect is significant, but the pesticide residue is large, resulting in contaminated quality of jujube. Therefore, the application amount of chemical pesticides should be reduced as much as possible, and biological pesticides and agricultural and physical methods should be actively used for comprehensive prevention and control, such as black light, frequency vibration type insecticidal lamp, sweet and sour liquid and artificial capture.

Can not ignore the ground to kill a considerable number of jujube farmers only pay attention to spraying on the tree, and ignore the block on the ground. Because the soil is the overwintering or hiding place of eggs, cockroaches, larvae, and some adult pests of most pests and diseases, the use of effective pesticides to kill the ground may play an extremely important role in the prevention and control of pests and diseases throughout the year.
