Like orchards, there are taboos on the use of pesticides. For the sake of the health of the people, what I have learned about pesticides banned in orchards is as follows:
1. Dimethoate and Omethoate: Apricot and Li are sensitive to the EC with a dilution factor of less than 1500 times. They should be used for community trials first, and then used in large areas after safe use.
Second, trichlorfon, dichlorvos: on the stone fruit trees have great phytotoxicity, should not be used; on the Golden Delicious, Marshal, brocade, chicken cocks and other apple varieties have phytotoxicity; used in other apple trees, should be in the young fruit period (Post-flower and physiological fruit drop) spray.
3. Phosphamidans: Peach trees are sensitive to them and should not be used.
4. Insecticidal ring: Some fruit varieties are sensitive and should be tested for phytotoxicity before use.
Fifth, rice flour scattered: peach, grape, apple varieties sensitive to it, easy to produce phytotoxicity, should not be used.
Six, dicofol: Hawthorn and apple varieties of red jade, Xuguang sensitive, easy to produce phytotoxicity, should not be used.
VII. Keziol, Keke: The pear tree is sensitive and should not be used.
8. Arsenic preparations: Certain varieties of stone fruits, apples and pears are prone to phytotoxicity and should not be used.
Nine, Bordeaux mixture: Peach, Li, hawthorn sensitive to the growing season, regardless of what kind of preparation are prone to injury; when the lime in the Bordeaux mixture is less than the amount of type, the pear, apple, apricot easy to produce injury; hawthorn Spraying after flowering and during apple fruit growth, fruit rust is heavier and should not be used; apple medicine should be used as late as possible during its growth.
X. Lithosulfur mixture: Peach, plum, apricot, grape, pear, etc. are used when young tissue is prone to phytotoxicity and should be used cautiously or avoided.
Eleventh, glyphosate, Gramoxone: are all herbicides, all fruit trees are sensitive to them, can not be used in fruit trees, can only be used for directional spray between fruit trees weeding. Apricot trees are sprayed with this herbicide to prevent weeding. It is very easy to produce phytotoxicity and herbicide should be prohibited.
