Glufosinate Ammonium | Glyphosate | |
Mode of action | acts on contact, The mode of action of glufosinate-ammonium occurs as a result of the inhibition of the enzyme glutamine synthetase. This causes a build up of ammonium ions in the plant's tissues that prevents photosynthesis. | Systemic and translocating. Its mechanism of action-inhibits enolpyruvyl shikimidin phosphate synthase, protein synthesis is hindered |
Speed | Works very quickly (24–72 hours) | Works slowly (7–14 days) |
Selectivity | Broad-spectrum, glufosinate tends to be more effective on annual broadleaf weeds than annual grasses. However, high-effective on Glyphosate-Resistant Weeds, such as eleusine indica, horseweed herb. | Controls broadleaf weeds and grasses more than 160 kinds of weeds. Glyphosate is more effective on grasses besides perennial resistant weeds. |
Safety performance | The glufosinate has no influence on the soil, the root system and the subsequent crops. Long lasting period. Not easy to drift. Safe to the crops. | Glyphosate should not be used on crops with shallow roots or exposed roots, such as coriander, pepper, grapes, papaya, etc. |
Safety interval | Can sow or transplant after 2-3 days of application | Can sow or transplant after 7 days of application |
