Licorice phosphorus herbicide belongs to sterile, systemic and post-seedling stem and leaf treatment agent. Glycyrrhizic acid is rarely used in production, but its salts are widely used. At present, ammonium salt, sodium salt, potassium salt and isopropyl ammonium salt are mainly used in China.

Usage technology: The registered dose of products from different salts and manufacturers may be different, which is generally1125 ~ 2250g (a.i.)/hm2, which is equivalent to 750~ 1500ml of ammonium glycyrrhizinate solution.

It should be noted that 12% glyphosate aqueous solution is glyphosate plus synergist, and its registered dosage is only 450~594g(a.i)/hm2, which is equivalent to 250~330ml preparation.

Extended data:

First, powder. Powder is insoluble in water, so it cannot be sprayed with water. Low concentration powder is used for spraying, and high concentration powder is used for preparing toxic soil, bait, seed dressing and soil treatment. Powder is easy to use and has high working efficiency, so it should be used in the morning and evening when there is no wind or the wind is weak.

Second, wettable powder. Strong hygroscopicity, can be dispersed or suspended in water after adding water. Can be use for spraying, poison bait and soil treatment.

Three, soluble powder (water solvent). Water can be sprayed or poured directly.

Four. Emulsion (also called emulsifiable concentrate). Emulsion is an emulsion added with water, which can be used for spraying, root irrigation, seed dressing, seed soaking, toxic soil, stem coating and so on.

Five, ultra-low volume preparation (oil). It is a drug directly used for spraying and a special supporting pesticide for ultra-low volume spraying. You can't add water when you use it

Six, granules and granules. It is a granular pesticide preparation made of pesticide raw materials and fillers, which is not easy to cause phytotoxicity. Mainly used for leaf filling, spreading, spot application, seed dressing, furrow application, etc.

Seven, sustained-release agent. When in use, the pesticide is slowly released, which can effectively extend the validity period. Therefore, the residual period is prolonged and the pollution and toxicity are reduced. The usage is generally the same as that of granules.

Eight, smoking agent. Smoke agent is fine powder or ingot made of pesticide, fuel, oxidant, combustion improver, etc. This pesticide is vaporized by heating, and then condenses into solid particles in the air, forming a smog shape, which is mainly used to control pests in forests, protected agriculture and warehouses.
