(1) Phosphamidase: It is harmful to peach trees and should not be used on them.
(2) Methyl dichloride: This chemical is toxic to a wide range of fruit trees and should be avoided on all types.
(3) Dichlorvos: Not recommended for use on stone fruit trees due to its high toxicity.
(4) Dimethoate and Omethoate: These insecticides are particularly sensitive to peaches and pears when diluted below 1500 times. A small-scale test should be conducted before full application to ensure safety.
(5) Inagi powder: Certain peach and grape varieties are highly sensitive to this product, so it should be used with caution.
(6) Konke and Kete Special: This formulation is strictly prohibited for use on pear trees.
(7) Tian An and Arsenic Preparations: These products are not suitable for certain stone fruits, citrus, and pears due to potential phytotoxic effects.
(8) Glyphosate and Gramoxone: Both are non-selective herbicides that can cause severe damage to fruit trees. They should only be used in targeted areas between trees, not directly on the foliage.
(9) Shiliu Mixture: This mixture has a high risk of causing phytotoxicity in young tissues of grapes, peaches, and pears. Careful application is required.
(10) Bordeaux Mixture: Peach and plum trees are sensitive during their growing season. The mixture contains lime and copper sulfate, and when applied at concentrations lower than the recommended ratio, pears and persimmons may suffer from phytotoxicity. Conversely, if the concentration is higher than the standard formula, grapes may also be affected. Always follow the recommended dilution rates to avoid damage.
This information is essential for farmers and agricultural workers to ensure safe and effective use of these chemicals while protecting fruit tree health and productivity. Always read labels carefully and consult local agricultural guidelines before application.
