Recently, the farmers on our side have discussed that rice borers cannot be killed, cannot be extinguished, and the control effect is not good. Rice in the Yangtze River Basin has 1-4 generations of rice borer hazards, rice longitudinal leaf borer also has 3-5 generations of hazards, rice longitudinal leaf borer commonly known as "rice balsaparab", dihua borer, three-way borer commonly known as "drill heartworm", spray control is difficult, it is difficult to exterminate, if you do not grasp the best time for prevention and control, the prevention and control effect is almost ineffective. In addition, it is also necessary to choose the right medicine, choose to suck and kill, smoke and kill the effect is better. Prevention methods are also key.
<h1 class= "pgc-h-arrow-right" > first, grasp the critical period of prevention and control, and prevent problems before they occur</h1>
Many farmers control rice borer is found to have white spots or albinism in rice leaves to control, in fact, rice has white spots to prove that rice has been endangered, borers have been drilled into the leaf sheath, rice longitudinal leaf borer has been wrapped in rice leaves, the liquid is difficult to spray to the insect body, touch killing agent is difficult to play a killing role. In the prevention and control of the disease to prevent the occurrence, from the beginning of the tillering of rice every 7-10 days spray control, when found that there are adult insects migrating and flying in the rice field to spray control, do not wait for the eggs to hatch into larvae and then control, there is no pest and disease to prevent and control. Like our farmers found that the leaves were bleached and the leaf tips became white spots, the spray control may be late, and the prevention and control effect is naturally not good. Prevention and control of planthoppers, rice longitudinal leaf borers, and dihua borers in August is the best time to prevent and control until early September. The effect of killing feathered adult insects is better, and it can play a multiplier effect with half the effort.
<h1 class="pgc-h-arrow-right" > second, it is also important to choose the right drug</h1>
Your rice pest control effect is not good, which may be related to the choice of medicine. We farmers are accustomed to choosing commonly used agents, or choosing to use a certain kind of agent for a long time, so that diseases and insect pests have developed resistance and resistance. "Rice balsam" and "drill heartworm" parasitize in the leaf wrapping or drill into the internal hazards of the rice stem base, and the prevention and control of the touch killer is naturally a little worse, if you choose to suck and kill, the smoke and kill agent may have a better effect. Spray prevention and control mixed spray effect will be a little better. A variety of agents alternately rotated to achieve the effect of prevention and control. When spraying, leave the water layer of the rice field a little deeper, and keep it for about 5 days without irrigation or dry water. Develop the habit of using new drugs and control them in accordance with the guidance of local plant protection stations. For example, farmers on our side have rarely used insecticidal double, insecticidal single, acetamiprid, thiamethoxam, dichlorvos, and now use chloranthramide, furanamide, ether ester, methylaminoavermectin benzoate, tetrachloroamide, trifluorophenylpyrimidine and so on.
<h1 class= "pgc-h-arrow-right" > third, the spray method is also critical</h1>
For the prevention and control of rice longitudinal leaf borer and rice borer, spraying should pay attention to methods and methods at this time. The spray is as far as possible to align the leaf shoes, the nozzle is facing down, and the swirling water flake in the nozzle is removed. At this time, the prevention and control of diseases and insect pests does not need to be too atomized, but the agent needs to be stored in the leaf sheath, so it is necessary to spray the full dose and sufficient potion. The potion flows into the leaf-wrapped area to achieve the purpose of killing pests and diseases. Your family's pest control is not good, it may be that you are too lazy to take off the swirling water tablet, and the atomization immediately evaporates. Or the nozzle is pointed upwards, spraying the back of the leaf, and the leaf sheath is not sprayed, and the larvae in the stem base cannot be poisoned and die. Some people have not entered the industry for a lifetime, may not even be standard for spraying, or self-righteous, and do not humbly seek advice, do not shame to ask, and the crops are worse than other people's families every year. Spray or group prevention and group control, everyone unified time prevention and control effect is better, your family retreats to control, may be diseases and pests have migrated to your family's rice field, the consequences are unbearable. To prevent and control diseases and insect pests, it is still necessary to kill insect eggs at the same time, and only by killing insect eggs can we draw salaries from the bottom of the pot. If the eggs are not sterilized, it is still ineffective, and the diseases and insect pests still have to be more serious.
