Pistachios are delicious tree nuts recognized for their nutritional qualities. Pistachio nuts are a rich source of energy, vitamins, minerals, and many phyto-chemical substances with antioxidant properties. Pistachio nut oil features flavorful, pleasant nutty aroma and has excellent emollient features. It helps to keep skin well protected from dryness. Today pistachio trees can also be found in India, Pakistan, Iran, Afghanistan, Tajikistan, Lebanon, Greece, Turkey, Egypt, Italy and the USA.
Pistachio trees are highly vulnerable to weeds that weaken the plants’ resistance to a number of diseases, insects and mites, which can damage entire pistachio orchards. The competition between pistachio and weeds is of greater concern when trees are young because weeds can delay growth and production. Additionally, weeds can host pests and pathogens, interfere with irrigation uniformity and distribution, and reduce harvest efficiency.
Glufosinate-ammonium is a highly effective tool for controlling a broad spectrum of weeds in pistachio trees and has thus enabled a significant increase in yields over the last three decades. The herbicide is applied around the pistachio trees and even if small amounts land on crop leaves there is minimal to no damage. The use of Glufosinate-ammonium as an alternative to commonly-used Glyphosate helps to avoid problems of weed resistance in pistachio.
