In the process of planting agricultural crops, some diseases are often encountered. Whitefly is one of them. It is an important pest for planting crops in greenhouses. It occurs in all parts of China. Let's take a look at the control methods of whitefly.
Today, we will teach agricultural friends some ways to effectively prevent and treat white meal.
Choosing crops: In areas where white flour is easy to occur, crops should be selected from crops that are cold-tolerant and not suitable for white flour, such as spinach, rapeseed, and garlic.
Eradication of insects: In the early stage of planting, preparations should be made to eradicate the source of insects. Insecticides should be used to spray insects, and the weeds remaining in the shed can be removed in time. The venting net can be set up to prevent insects from moving in.
Repelling and trapping: In the initial stage of whitefly, yellow sticky board can be used to trap adult insects. Because whitefly is more yellow, it can also be coated with oil to trap adult insects, and a reflective curtain can be installed indoors to drive white powder.
Launching Cao Ling: Cao Ling is one of the main predatory natural enemies of pests. It can effectively kill whitefly. We can put a certain amount of Cao Ling to prey on whitefly in the boron room.
Drug control: 1 In the early stage of the occurrence of whitefly, timely use of drugs, especially in the stage of spotting, we can use imidacloprid, chlorpyrifos EC. When the amount of insects is too much, we can add a small amount of pyrethrum vinegar to the liquid. Insecticides. And spray once every 5-7 days, repeated use can effectively kill whitefly.
2 We can also use imidacloprid and Wanling (Meduowei) to mix, the efficacy of methomyl is short, and the effect of imidacloprid is delayed. At the same time, it can make up for the problem of combining the two drug effects. Adding anti-antibiotic can further improve the drug. The whitefly that kills all kinds of insects is also used once every 5-7 days, and satisfactory results can be obtained.
The above is some ways for the majority of agricultural friends to sort out the prevention and treatment of white powder mites. Welcome to planting friends can refer to it, and timely prevention and treatment of various diseases is the key.
The efficacy and role of small molecule peptides:
1. The small molecule peptide has a simple structure and small molecular weight, the cell membrane can freely penetrate into the cell, and the cell absorption and utilization efficiency is high;
2. Small molecule peptides participate in the synthesis of enzymes, but also increase the activity of enzymes and promote the smooth progress of biological reactions;
3. Small molecule polypeptides can improve the permeability of gastrointestinal mucosa, capillary walls, alveoli and other intermediate metabolic membranes, so as to better absorb nutrients, filter toxins, and prevent the invasion of pathogens;
4. Small molecule peptides can also synthesize specific proteins and produce special effects in the body. At the same time, small molecule peptides can not only supplement the nutrition of cells, but also improve the function and state of cells.
