Orchard "spring spray" fight drugs?

Spring is the beginning of the new year and at the same time it is a critical moment for the prevention of pests and diseases in apple trees. In order to prevent insects from infesting the apple trees in the later period, and also to prevent the occurrence of branch diseases such as ringworm disease, dry rot, and rot disease, the most important task at present is to do a good job of "spring spray."

The so-called "spring spray" refers to spraying before germination (dry shoots). In the past few years, a lot of fruit growers had a big misunderstanding about the prevention and control of diseases and insect pests in the dry season. It was thought that the dried branches were merely for the prevention of rot disease, and it was thought that playing the medicine would not be very effective. Practice has proved that this kind of understanding is wrong. In recent years, the deterioration of trees caused by soil acidification and other factors has caused more and more serious diseases such as rot disease.

In March and April, it is the peak period of rot disease of fruit trees in the whole year. Therefore, the medicine for controlling rot disease in the budding stage must be played. In addition, on the stems of fruit trees, there are lurking loops, anthrax, and other pathogens, as well as pests and their eggs of ticks and scale insects such as red spiders. At this stage, they must also use drugs to kill all pathogens and eggs. Off.

Dry shoots not only have to fight, but also a good fight, we must hit the "wet, thorough, flow" standard, an acre of 400 pounds of syrup. This time medicine is being used, it is equivalent to killing pests and diseases in the cradle, and at least about 70% of the survival rate can be eliminated, which can greatly reduce the pressure of pest control throughout the year. In the prevention and control of pests and diseases, we advocate "treating early, treating less, and treating the disease," and trying to "do everything possible to prevent it from being cured."

Dry branching period is the season of exchange, it is easy to appear late spring, especially in the cherry during this period is very easy to cause freezing damage, so must be combined with drying branches medicine, which added 500 times "European" +500 times "flower face Kang ” Enhance tree immunity and frost resistance. At the same time, 200 times more “oligosaccharide zinc” can be added to solve the lobular disease for the lobular disease.
