The killer of fruit tree ring disease - Baitai
Not long ago, Wang Yingzi, a researcher at the Plant Protection Institute of the Agricultural Science Institute of Yantai City, Shandong Province, came to teach the apple tree planting management technology at the foot of Mengshan. When he entered the orchard, Wang found a problem immediately.
"I think the apple ring disease on this tree is more serious." Teacher Wang pointed to the disease caused by the ring disease on the tree. The ring disease is like a spy. It is "latent" in the disease on the tree. Waiting for the opportunity to attack. After the apple is thankful, when the air is wet and raining, the tumor is broken. These spies will fly to the branches and young fruit to continue. "Hidden." When the apple is close to the maturity and storage period, it will start to destroy and cause the rotten fruit.
Apple ring disease should be prevented from the beginning of the flowering period and the young fruit period. It is now a flowering period, and it is necessary to spray the first drug control 7 to 10 days after the apple Xiehua. In recent years, 60% of Baitai water dispersible granules have been tested very well, with a drug efficacy of over 94%. Compared with mancozeb, the chlorophyll content of spraying three times (Bai Tai) can be increased by 17.6%.
Baitai is a new broad-spectrum fungicide developed and produced by BASF in Germany. Its main components are pyrazone and Daisenlian, which have both protective and therapeutic effects. It has five major advantages:
First, it is very broad-spectrum and has a very good preventive effect on the main diseases of apple trees. Valid for 10 to 15 days, longer and very resistant to rain.
Second, it can increase the chlorophyll content, make the leaves turn green and enhance photosynthesis.
Third, the Baitai dosage form is very advanced. It is not precipitated in the water. The particles are extremely fine. It is sprayed onto the apples and does not stimulate the fruit. The apple's surface is very good.
Fourth, it can improve the immunity of plants.
Fifth, it can help plants resist drought, resist high temperatures, resist cold and resist aging.
The usage of Baitai: Spray the first time in 7~10 days after apple Xiehua, spray the second time around 10 days, usually spray 1~2 times before bagging, 1500 times liquid spray.
However, the product does not recommend continuous use, and other products can be interspersed. (Yang Guang)
