"Glyphosate" is an herbicide, how it increases sugar recovery?

Question

"Glyphosate" is an herbicide, can some one explain how and howmuch of this chemical is used for increasing sugar recovery per hector?

This has referance to the answer for the question "How can I increase sugar recovery in sugarcane?" asked recently on this section.

Answer 1

While the first answer is true, I believe she was referring to the method of applying Glyphosate about 10 days before harvesting the cane. It brings the cane into early maturity at a much higher sugar concentration than if left to mature on its own. It also dries the leaves up on the cane stalks, sending the cane to the mill with much less trash. I believe that they are claiming this method increases the recovery of sugar about 20% over not using the Glyphosate.

Answer 2

i believe john h is partly right. Glyphosate although a herbicide, when applied to any plant, eventually hastens its maturity, therefore producing sucrose in its stalks.
Glyphosate or roundup when used interferes with the plants vegetative growth, which can be seen in the yellowing of the older leaves first. Although it requires 2-3x spraying spread out, usually it takes 30 days to eventually kill the plant.
But if your objective is to increase sugar recovery, 1 application might do, i think. I've used round-up but for killing really persistent weeds.
It speeds up the aging process of the whole plant. Therefore when applied to sugarcane, and harvested at the right time would yield an increase in sugar recovery...

Answer 3

Glyphosate increase the translocation of sugar from leaf to stem in sugarcane plant.

Answer 4

It is used for weed control thereby increase to amount of sugar per hectare; not for extraction of the sugar.

Check this link. It is the testing of Glyphosate for weed control in cane fields. (around page 42)

Trade names for products containing glyphosate include Gallup, Landmaster, Pondmaster, Ranger, Roundup, Rodeo, and Touchdown. It may be used in formulations with other herbicides.

Glyphosate is a broad-spectrum, nonselective systemic herbicide used for control of annual and perennial plants including grasses, sedges, broad-leaved weeds, and woody plants. It can be used on non-cropland as well as on a great variety of crops. Glyphosate itself is an acid, but it is commonly used in salt form, most commonly the isopropylamine salt. It may also be available in acidic or trimethylsulfonium salt forms. It is generally distributed as water-soluble concentrates and powders. The information presented here refers to the technical grade of the acid form of glyphosate, unless otherwise noted.

Hope this answers your question.

Good Luck.

Answer 5

Removing weed competition in any crop increases the per hectare harvest. Weeds will more often than not take up the soil solution faster than the crop intended. That effectively reduces the availability of water and nutrients (fertilizer) and decreases the yield and quality of it.
