CAS Registration No.: 1071-83-6

Specification:

Technical Grade; Active Ingredients: Not less than 95%,Aqueous solution:41% 62%

Glyphosate is an acid, but it is commonly used in saltform, most commonly in isopropylamine salt anddimethylamine salt.

Toxicity Status:

Low toxic to both human and animals.
Oral LD50 (Acute) Rat: 4320mg/kg
Dermal LD50 (Rabbits): >7940mg/kg
Eye & Skin Irritation (Rabbits): Slight
No abnormal symptoms were observed when it wasadministered at 2000mg/kg for 90 consecutive days.Carcinogenic, mutative and teratogenic effects werenot detected. Low toxic to fish, bees and birds. Thetoxicity data LC50 for rainbow trout and water flea were established at not less than 1000mg/kg and 80mg/kg respectively.

Mode of action:

The broad-spectrum systematic & conductive and non-selective herbicide is characterized by high efficiency, low toxicity and high safety. It is intended for control of deep-rooted perennial weeds. Glyphosate applied to foliage is absorbed by leaves and rapidly moves through the plant. It acts by preventing the plant from producing an essential amino acid. This reduces the production of protein in the plant, and inhibits plant growth. Glyphosate is metabolized or broken down by some plants, while other plants do not break it down. Aminomethylphosphonic acid is the main break-down product of glyphosate in plants.

Target Plants:

Initially intended for oak trees to enhance growth rate and meanwhile widely used for forestry, fruit, tea plantations and mulberry gardens and fields as well as field edges, roadside and railway margins. Glyphosate is used to control grasses, herbaceous plants including deep rooted perennial weeds, brush, some broadleaf trees and shrubs, and some conifers. When applied at 0.7-5.6kg/hectare it exhibits good effects. When applied during the period of full growth, it exhibits rather strong control effects against most of the targeted weed.

Scope of Application:

Intended for forestry, fruit, tea and mulberry gardens and fields as well as field edges, roadside and railway margins. Glyphosate is used to control grasses, herbaceous plants including deep rooted perennial weeds, brush, some broadleaf trees and shrubs, and some conifers in fruit gardens and farms that have been refreshed. It is applied before harvest time. It is suitable for fully-grown cotton, small grains, peas and soybeans.

Application:

1.Annual Weeds Control in Fruit & Mulberry Gardens : 0.5-1kg aqueous solution 10% /acre for annual weeds; 20-30kg aqueous solution 10%/acre for perennial weeds; Directional spraying
2.Weeds in Field before rotation: Refer to Section 1.When applied to cotton, it is spayed directionally with the protection of shield. 0.5- 0.75kg aqueous solution 10% per acre by diluting with 20-30kg of
water.
3.Weeds on grasslands, field edges and roadside: 0.5-1.0kg aqueous solution 10% per acre by adding 100ml of diesel and diluting with 20-30kg of water. Directional spraying is essential.

Precautions:

Even spray is essential because it can only be absorbed by green leaves and young parts of weeds. Directional spray is necessarily required to prevent unintentional damage caused by spraying on non-target plants. Apply again when it rains within 4 hours. It should be stored in plastic containers because of its corrosiveness. Direct contact with metal should be avoided. When stored under low temperature, it has blending substances. To maintain its effectiveness, shake the container well and let crystals dissolve completely.
Glyphosate is an effective herbicide. Cross-contamination should be prohibited when it is being handled.
For perennial weeds, effective treatment and prevention can be achieved 1 month after the second single application. The interval between the two replicate applications is one month.
The effectiveness can be improved by adding diesel or detergent agents.
The results would be better when it is applied in a hot fine day. If it rains within 6-8 hours, apply once more.

Storage: Kept in a cool dry place.

Expiration Period: At least two years.

Packaging: Iron or fiber drums. Make adjustments according tocustomers' requirements.
