10 Pesticides Fruit Trees Should Never Use - Fruit Growers, Stop Using Them

Diammonium phosphate: forbidden for peach trees.

Diquat: forbidden for all kinds of fruit trees.

Dichlorvos: forbidden for stone fruit trees.

Dimethoate and omethoate: peach and pear are sensitive to spray solutions diluted less than 1500 times, so test first before use to determine a safe concentration.

Phenthoate: some varieties of peach and grape are sensitive to it, so use it with caution.

Amitraz and propargite: forbidden for pear trees.

Tianan and arsenic preparations: must not be used on stone fruits, citrus or certain varieties of pear.

Glyphosate and Gramoxone: both are non-selective herbicides and cannot be used on any kind of fruit tree; use them 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 it 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 multiple-dose formula, pear and persimmon are prone to phytotoxicity, and when it is higher than the equal-dose formula, grape is prone to phytotoxicity.
