Note: 1. Acaricide Acaricide: Pear trees are sensitive and cannot be used.
2. Bordeaux mixture: peaches and plums are sensitive to it during the growing season. When preparing Bordeaux mixture, pears, apricots and persimmons whose ratio of lime to copper sulfate is lower than that of double-dose formula are prone to phytotoxicity.
3. Sulfur mixture: Young tissues of peaches, plums, grapes and pears are prone to phytotoxicity, so pay attention.
