The difference between glyphosate and glyphosate

glyphosate and glufosinate are herbicides, although they are only one word difference, but there are essential differences, many people will confuse them, here is to introduce the difference between glyphosate and glufosinate.

1, glyphosate is amino acid, inhibit enolacetone shikimine phosphonic acid synthase, protein synthesis is disturbed, with internal absorption conductivity, mainly kill roots; glufosinate ammonium is phosphonic acid, ammonium accumulation contact kill, inhibit glutamine synthesis, mainly contact kill, internal absorption is weak, first kill leaves can be leaf conduction.

2, glyphosate is widely used in rubber, mulberry, tea, orchards and sugar cane fields (generally not used for shallow roots or root exposed crops, such as vegetables, coriander, pepper, grapes, papaya, corn, etc.), generally 7-9 days effective, 15 days dead grass; glufosinate can be used for all crops but can not be sprayed on crops, generally 3-5 days effective, 7-10 days dead grass.

3. Glyphosate-resistant weeds such as Adrenaline grass and Erigeron canadensis have poor control effect, and resistant weeds increase year by year; glufosinate has good control effect on resistant weeds such as Adrenaline grass and Erigeron canadensis, but has poor control effect on Cyperaceae weeds in some areas.

4, glyphosate is easy to lead to the lack of trace elements in the soil, crop deficiency, and improper use is easy to drift phytotoxicity, affecting crop growth; glufosinate negative effect is relatively small, no harm to the soil, liquid drift only in the contact position to produce drug spots, little impact on crop growth and yield.
