It rained the first two days. Have we done any pest control? Many fruit growers look good and don’t do it. But when I got sick, I regretted it after I grew up. Because this time the grapes are in the second and third leaves, because we just had the rain a few days ago, the pests and diseases began to rise after the rain. First, the grapes just came out, the resistance is relatively poor, the second, the spring The temperature changes drastically. At this time, many diseases are invisible, so if we don't prevent it, when we see it later, it will cause great damage to our grapes.
Therefore, we focus on the green blind cockroaches, that is, when the spring leaves are relatively tender, because the green cockroaches are particularly fond of eating tender things, we should not underestimate the little worms, if the leaves that have just grown are affected. The infestation of the green blind scorpion will seriously endanger the normal growth of the leaves. We must eliminate it in advance, and there are many drugs against green blindness. People in our Longkou area are more willing to use omethoate and chlorpyrifos. This medicine is effective against the green blind mites, but it also causes damage to the leaves. After the leaf damage, the leaves are bright yellow spots or oily yellow spots. After the leaves are damaged, the roots of the leaves are rooted. Great impact.
For green blind mites, we can also use Kung Fu thiamethoxam or imidacloprid thiamethoxam, including agents such as biphenyl and acetamiprid. The period of validity can be longer, about 8 to 10 days. If the phenomenon of green blindness has been discovered, try to ensure that the drug is sprayed once in seven days, and the green blind must be completely eliminated to avoid harm. In the prevention and control of pests, the disease of grapes can not be ignored. This period of prevention and treatment mainly prevents black pox disease, because black pox disease is infecting young tissues, including downy mildew and white rot. For the red-lift, in the past two years, we have early spring ulcer disease in the early spring of Jiaodong Peninsula. So how can we prevent and cure these diseases? If we are fighting black acne, last year white rot is more powerful, we can use difenoconazole or methyl thiophanate, the effect is very good.
The most important thing is prevention. If it is treated with light, it lasts for a short time. We should better use a protective agent, such as azoxystrobin or pyraclostrobin. Like the variety of gemstones, we can add isoflurane to increase the control of this cut gray mold. Some vineyards are close to planting peanuts and wheat. When spraying peanuts and wheat, you must take care to avoid harm to the grapes. Therefore, it is best to add auric acid ester or brassinolide when we fight drugs, in order to reduce the harm of herbicides to our grapes.
