ECOLOGICAL APPROACH FOR WEED CONTROL IN YOUNG PEACH PLANTATIONS

Best weed management control was studied at the Fruit-Growing Institute in 2007-2008 in a young peach plantation including the cultivars ‘Ognyanka’, ‘Fileta’, ‘Elite No. 482’ and ‘Elite No. 23-15’. In spring, before vegetation, the in-row strip was treated with the contact leaf and soil herbicide oxyfluorofen.
Directed application of glyphosate was made twice during vegetation for control of secondary (late) weed infestation.
The applied herbicide combination of oxyfluorofen and glyphosate achieved very good herbicide efficiency against the weed species forming the weed association in the row strip of the plantation.
The period of an efficient herbicide post-effect of oxyfluorofen lasted about 120 days.
External symptoms of phytotoxicity and suppression of the vegetative and initial reproductive habits of the peach trees were not established.
The use of oxyfluorofen and glyphosate did not entail any risk of contaminating the environmental components with pesticide residues.
That is a good reason to apply the herbicides oxyfluorofen and glyphosate for ecologically sound weed control in young peach orchards.
