Reliance on drugs alone is not desirable In fact, if we want to completely eradicate the mentality of pests, we will take the wrong direction in the prevention and control of farmers' pests and diseases, and enter a vicious cycle of relying on chemical control. Some dealers often cater to the needs of farmers. Neglecting the pest prevention and control needs to find the best timing, multi-measures and other technical guidance. By default, farmers can increase the dose, multi-class mix, and high-frequency spray at will, so that any new insecticide can be used. After the agent is put into production and use, pests quickly develop drug resistance, leading to a decline in the efficacy of the agent. Understanding the law of pests is the key Chemical control is one of the measures to prevent and control pests, but it is not the only one. Occurrence of any kind of pest is regular, such as where to come from, when to lay eggs, when to hatch, when the larvae are at the peak of the growth stage of the vegetables, where the adult insects like to lay on the crop, lay eggs, and larvae. Which organs of the crop do you like or dislike, temperature and humidity lighting, and crop nutrient effects on larval development? Understanding these laws of occurrence of pests, combined with the cultivation of crops and their growth and development rules, can only take effective prevention and control measures and means. For example, by adjusting the sowing date or the time of planting, it is possible to stagger the peak period of egg laying of pests; by interplanting other crops that pests do not like or prefer, they can repel or trap pests; traps can be trapped by setting yellow plates, sex trap traps, etc. Insect pests can be used to regulate the growth of crops by "rejecting" pests by feeding them; using seeds or seedlings, pesticides, soil agents, and the use of different agents can reduce the frequency of pesticide application, improve efficacy, and save time and labor. Wait. Take the yellow stripe jumps for example Life habits and feeding habits of yellow striped armor Yellow striped hops like to harm mustard, pakchoi, radish and other cruciferous vegetables, because these vegetables will emit a kind of yellow song strips adult worms like biochemical material - mustard oil. Adults spend winters underneath vegetable residues, soil gaps and weeds. The wintering adults start feeding when the temperature returns to 10°C in the spring of the following year. Adult insects are good at jumping, and they are evasive in case of alarm. They hide in the back of the leaves and clods in the morning and evening or rainy days. When the temperature is high before and after noon, the activity is the most prosperous. Adults mainly damage the leaves, feed on the leaves, and bite out many holes in the leaves. Adults like the young part of the edible plants, so the seedlings suffer heavy damage, especially the newly emerged seedlings. However, adults do not produce eggs on vegetables, but on soil particles near the roots of the plants. After the larvae hatch, they move down the roots of the vegetables while biting the epidermis, resulting in the roots of the vegetables. The appearance of "face blemishes" can easily induce soft rot. After the larvae are matured, soil maggots are made at 3 to 7 cm below the soil. The Yellow Striped Armor enjoys a warm and humid environment. When the temperature drops or exceeds 30°C, it stops moving. Effective control measures If you understand the basic information of the yellow song strip, there is a general direction in the prevention and control strategy. First, the warm and humid season in spring and autumn is the best time for prevention and control, especially after the emergence of spring seedlings, as long as the number of insects is suppressed, the initiative can be achieved on the prevention and control of the whole year; secondly, sexual attractants and yellows are set in the fields. The board traps cockroaches adults and uses the characteristics of the adults like yellow and sex pheromone to combine yellow with sex attractants to increase the trapping force of adults. Third, the pesticide soil is layered and the current insecticide particles are large. Most of them are based on contact toxicity. Stratified soil treatment allows the granules to be evenly distributed in the vertical direction of the soil as much as possible, to increase the probability of contact between the pesticide and the worm body, and to control the occurrence of larvae and pupae. Fourth, to apply repellents on the soil surface. Effects of pesticides or fertilizers, such as avicanthin organic fertilizer; Fifth, in the adult stage sprayed with rotenone, avitratin and other "infertility" role of the plant-source insecticide, mixed Or alternately more rapid chemical synthesis of pesticides, such as bufalin, acetamiprid and so on. This "combination boxing" can better control the damage of the yellow string jumps. In order to save time and labor, farmers have to adopt an easy method of spraying insecticides to prevent and control pests. However, this cannot save a lot of time and effort. Therefore, in order to prevent, control, and control vegetable pests easily, effectively and safely, we must change our minds, look for the right timing for prevention and control, and effectively combine various means.

Insects are not good to prevent another idea
In recent years, the pests on cruciferous vegetables such as the yellow-trickle-jumped plucked and diamond-backed moth are becoming more and more difficult to treat. The pesticides such as deltamethrin, beta-cypermethrin, cyhalothrin, and bifenthrin have become history; Phosphorus, chlorpyrifos, profenofos, the effect is no longer; diflubenzuron, diflubenzuron, chlorfluazuron, tebufenozide, the advantages of loss; methomyl, indoxacarb, prestige is no longer; abamectin, Alkaline salt has not been brilliant for a few years; even if it is the chlorantraniliprole that swept the Chinese insecticide market, it will take two to three years and the efficacy will decrease rapidly. From the manufacturer to the distributor and then to the farmers, they are puzzled. The use of insecticides is getting higher and higher. How can we not cure small insects?
