Orchards using glyphosate should pay attention to several issues

Glyphosate is a highly efficient, low toxicity, broad-spectrum herbicide pollution. In recent years, with 10% glyphosate controlling weeds in orchards, and achieved good results. Started one week after using glyphosate markedly ,10-15 parts dry death on earth, a month or so underground brown rot, weed effect of 100%, a drug can reach extermination purposes. But orchards using glyphosate herbicide, should pay attention to the following questions:
1, pay attention to the quality of spraying. Herbicide Glyphosate is the contact green organizations that exert cytotoxicity. Therefore, the requirements of spray nozzles when spraying down weed liquid sprayer evenly thoughtful as close as possible to prevent spray mist drift on fruit tree branches to avoid injury. In particular, sensitive to glyphosate apricot, prone to injury, therefore, apricot using glyphosate more must be cautious.
2, note that according to weed species to determine the amount of glyphosate. Weeds to glyphosate due to various different sensitivities, so different dosage. On annual weeds such as crabgrass, pigweed, barnyardgrass, goosegrass, foxtail, etc., the amount per acre with 10% glyphosate 500-700 ml; against plantain, small canadensis, Commelina per acre you need to 800-1000 ml; against perennial weeds such as Imperata, reeds, thorns vegetables, alkali grass, etc., required to 750-1000 ml per acre. According to the above dosage, dosage watered 20-30 kg per acre for grass targeted spray can. If spraying detergent added 50 grams, 150 grams of diesel, mixed evenly sprayed herbicide force can be increased 1-3 times.
3, note that according to the different periods of medication. Suitable period of use of glyphosate in weed seed growing period prior to flowering period of time, spraying premature, because weed leaves smaller, less affected by the dose, the less weed root tissues damaged affect the herbicidal effects; spraying too late, ie reducing the herbicidal effect and the need to increase the dose and increase costs.
4, glyphosate corrosive to metal, should be kept in the storage and use of the use of plastic containers. After plastic sprayer spraying glyphosate, the sprayer must be repeatedly washed several times with alkaline water, then rinse with water, otherwise the ban to other fruit or other crops sprayed with pesticides.
