(1) Phosphamidase: This pesticide is harmful to peach trees and should not be used on them.
(2) Methyl dichloride: It is toxic to a wide range of fruit trees, causing damage or death. Avoid using it on any fruit-bearing plants.
(3) Dichlorvos: This chemical is prohibited for use on stone fruit trees such as peaches, cherries, and plums due to its high toxicity.
(4) Dimethoate and Omethoate: These pesticides are particularly sensitive to peach and pear trees when diluted below 1500 times. Before applying, it's essential to conduct a small-scale test to determine the safe concentration for use.
(5) Inagi powder: Certain varieties of peaches and grapes are highly sensitive to this product. Use with caution and consider alternatives if possible.
(6) Konke and Kete special: These formulations are strictly forbidden for use on pear trees due to their potential to cause severe damage.
(7) Tian An and Arsenic preparations: Some varieties of stone fruits, citrus, and pears are not suitable for these products. Always check compatibility before application.
(8) Glyphosate and Gramoxone: Both are non-selective herbicides that are phytotoxic to all types of fruit trees. They should only be used for spot treatment between trees, avoiding direct contact with foliage.
(9) Shiliu Mixture: This formulation can cause phytotoxicity to young tissues of grape, peach, and pear trees. Careful application is required, especially during active growth periods.
(10) Bordeaux mixture: This traditional fungicide contains lime and copper sulfate. Peach and plum trees are particularly sensitive during the growing season. If the concentration is too low, pears and persimmons may suffer from phytotoxic effects. Conversely, if the concentration is too high, grapes may also be damaged. Always follow recommended ratios carefully.
By following these guidelines, growers can minimize the risk of crop damage and ensure safer and more effective use of pesticides in orchard management.
