Which pesticides cannot be used on fruit trees? Please advise
The following introduces pesticides unsuitable for fruit trees:
Phosphamidon: avoid on peach trees.
Dichlone: avoid on all fruit trees.
Dichlorvos: prohibited on stone fruit trees.
Dimethoate, omethoate: peach and pear are sensitive to solutions diluted less than 1500 times, so test before use to determine a safe concentration.
Phenthoate: some varieties of peach and grape are sensitive to it, so use with caution.
Amitraz and propargite: prohibited on pear trees.
Tin arsenite and arsenic preparations: must not be used on stone fruit, citrus and some varieties of pear.
Glyphosate and paraquat: both are non-selective herbicides and cannot be used on any fruit trees, only for directed spraying between rows of fruit trees to control weeds.
Lime sulfur mixture: it easily causes phytotoxicity to the young tender tissues of grape, peach, pear and other fruit trees, so use with caution.
Bordeaux mixture: peach and plum are sensitive to it during the growing season; when the ratio of lime to copper sulfate in the Bordeaux mixture is lower than the double-strength formula, pear and persimmon are prone to phytotoxicity, and when it is higher than the equal-strength formula, grape is prone to phytotoxicity.
