Six Misunderstandings of Jujube Pest Management

First, pest control can not do group defense group governance: At present, most of the jujube farmers are still fighting for pest control, which leaves the opportunity for pest damage. Therefore, prevention and control of pests and diseases should be organized by grass-roots governments, associations, or voluntary organizations. Under the guidance of a skilled technician, unified pharmacy should be used, uniform spraying time, and group prevention and management in order to achieve the effect of killing or repelling pests. This will receive good results.

Second, the mechanism of the role of the agent is not allowed: Each pesticide has its role and function, if the understanding is vague, using the wrong agent, not only costs money, but also delayed the best period of control, with adverse consequences. Take the killing drugs: the same is the killing drugs, but there are differences in terms of use. Many juvenile farmers are confused about whether they kill eggs, kill nymphs or kill adult worms. For example, to kill winter eggs, you should use stunned nets or crickets, but you must not use scorpion spirits or broomstick nets. Otherwise, maggots will spread.

Third, do not understand the harm of pests Symptoms and occurrence of the beginning and prosperity: As many farmers often do not read, read less, do not know what the symptoms of jujube after the damage caused by pests and diseases, but do not understand the various pests At the beginning and the end of the season, the use of spraying time and the type of medicine used became problems. Just blindly watching other people sneeze his sneeze will often result in less work, not more. For example, Jujube Mosquitoes, from the point of view of recent years, in the middle and early April of Yuncheng area, when jujube trees began to sprout and develop leaves, juvenile mosquitoes started to appear, and their larvae sucked the juice from the tender leaves of young shoots, causing the wounded leaves to grow vertically. The affected area changed from green to red, hard and crisp, until withered. It is necessary to remind the juvenile farmers that once the disease is discovered, they should be immediately prevented and treated with effective pharmaceutical agents such as roxib, sirgreen, and shampoo.

Fourth, jujube fruit stop drug control after harvest: Most jujube farmers stop the jujube fruit after the stop of the chemical control, which increases the hidden dangers of the wintering base of the disease and insects, resulting in the proliferation of pests and diseases in the coming year.

Fifth, do not pay attention to comprehensive prevention and control, the use of chemical prevention and control: At present, jujube or pest control, the majority of jujube farmers still use chemical control, although the effect is more significant, but the pesticide residue, resulting in contaminated quality of jujube. Therefore, the application amount of chemical pesticides should be reduced as much as possible, and biological pesticides should be actively adopted, as well as comprehensive prevention and control of agriculture and physics, such as black light, frequency vibration type insecticidal lamp, sweet and sour liquid and artificial capture.

VI. Ignoring the ground blocking: A considerable number of juvenile farmers can not fully grasp the knowledge of controlling pests and diseases, and only pay attention to the spraying of pesticides on the trees, and they ignore the blocking on the ground. This is the biggest misunderstanding of the effective prevention and control of pests and diseases. Because the soil is the overwintering or hiding place of most eggs, larvae, larvae, or some adults of pests and diseases, the effective pesticide spray on the ground (especially when the spring pests emerge), which is extremely important for the prevention and control of pests throughout the year. The role.
