Excellent herbicide for gramineous weeds in cereal fields Clodinafop-propargyl
What is Clodinafop-propargyl(105512-06-9)?
The herbicide Clodinafop-propargyl is an organic compound with the chemical formula C17H13ClFNO4, Cas 105512-06-9 white crystal, soluble in organic solvents such as ethanol, ether, acetone, chloroform and other organic solvents. It is mainly used as a herbicide and can break down under strong acid and alkali conditions. The technical substance of Clodinafop-propargyl is a white crystal with a melting point of 48.2–57.1°C, a boiling point of 100.6°C (0.082Pa), a vapor pressure of 3.19 × 10-3 mPa (25°C) (OECD 104), and a specific gravity of 1.35( 20℃), solubility in water is 4.0mg/L (pH=7, 25℃), decomposition temperature is 105℃.Clodinafop-propargyl is soluble in organic solvents such as ethanol, ether, acetone, and chloroform.
Clodinafop-propargyl is a systemic conductive herbicide. The agent is absorbed through the leaves and leaf sheaths of plants, transmitted through the phloem, and accumulated in the meristem of the plant. It inhibits acetyl-Coenzyme A carboxylase (ACCase), stops fatty acid synthesis, and cells The growth and division of the plant cannot proceed normally, and lipid-containing structures such as the membrane system are damaged, eventually leading to the death of the plant.
The herbicide Clodinafop-propargyl-ethyl is used in cereal fields such as wheat, rye and triticale for post-emergence stem and leaf treatment to control annual grass weeds such as wild oat, black oat grass, foxtail grass, rye grass, and wheatgrass. The dosage is 30~60 g a.i./hm2.
Since Clodinafop-propargylhas low phytotoxicity to cereal crops such as wheat, in order to improve its safety to crops, Clodinafop-propargyl-Clodinafop-propargyl-propargyl is usually mixed with the safener clofenacet. The addition ofClodinafop-propargylcan ensure that cereals such as wheat, rye and triticale have excellent tolerance to Clodinafop-propargyl-propargyl. The compound ratio of Clodinafop-propargyl-Clodinafop-propargyl-propargyl and clofenacet-ethyl is usually 4:1. Topik is the product of this ratio. It is 240 g/L clodinfen-Clodinafop-propargyl-propargyl EC and 60 g/L clofenfofen-Clodinafop-propargyl-propargyl emulsifiable concentrate. , this product is an important brand product of Syngenta. Topik has a strong competitive advantage in the market, especially in the European and North American markets for the control of wheatgrass in cereal fields. In many other regions, wild oats are the main grassy weed problem in wheat production; and wheatgrass is a major problem affecting cereals in Northern Europe. main factor of growth.
The herbicide Clodinafop-propargylis relatively safe for wheat, and its application does not have high requirements on the age of wheat seedlings. Generally, it is required to apply when the wheat is at the 2-leaf and 1-heart stage to before jointing, when the weeds are basically all out and at the 2-4 leaf stage. When the grass age increases, the dosage should be appropriately increased. When weeds in the field are highly resistant, the dosage should also be appropriately increased. However, the pure medicinal dosage per acre should not exceed 9 grams, otherwise it will have adverse effects on the growth of wheat seedlings.
Compared with pesticides such as carboxyfop-propyl, which have a long application life, Clodinafop-propargyl has a better herbicidal effect, especially for weeds such as ragweed and hard grass that have developed resistance to carboxyfop-fen. It has good control effect; another advantage is its good adaptability to low temperature. Application of pesticides in low temperature environment will not have adverse effects on wheat seedlings (except for some spring wheat varieties). Although the weeding speed will slow down, it will not affect the final outcome. Prevention effect.
The herbicide Clodinafop-propargyl-ethyl has strong adaptability and can be compounded with a variety of herbicides to expand the herbicidal spectrum and even eliminate both grass and grass. The active ingredients compounded with it mainly include: pinoxaden, ethylbutoxyethyl chloride, trifluralin, octanoyl iodobenzonitrile, Benfenpyr, flufenoxyacetate, fluopyroxine isooctyl, 2-methyl-4-sodium chloride, bensulfuron-methyl+carmefenacet, diflufenac, bensulfuron-methyl+pyramethonen , bensulfuron and isoproturon, etc.

Advantages of Clodinafop-propargyl(105512-06-9)
Since Clodinafop-propargylhas low phytotoxicity to cereal crops such as wheat, in order to improve its safety to crops,Clodinafop-propargyl is usually mixed with the safener clofenacet. The addition of Clodinafop-propargyl can ensure that cereals such as wheat, rye and triticale have excellent tolerance to propargyl-propargyl. The compound ratio of Clodinafop-propargyl and clofenacet-ethyl is usually 4:1. Topik is a product under this ratio. It is 240 g/L Clodinafop-propargyl emulsifiable concentrate, in which 60 g/L clofenfenopyrazole is added. This product It is an important brand product of Syngenta. Topik has a strong competitive advantage in the market, especially in the control of wild oats in cereal fields in the European and North American markets, and has played an important role in the control of wild oats in Europe and many other parts of the world. Wild oat is a major grassy weed problem in wheat production; while wheatgrass is a major factor affecting grain growth in Northern Europe.
The herbicide Clodinafop-propargyl is relatively safe for wheat, and its application does not have high requirements on the age of wheat seedlings. Generally, it is required to apply when the wheat is at the 2-leaf and 1-heart stage to before jointing, when the weeds are basically all out and at the 2-4 leaf stage. When the grass age increases, the dosage should be appropriately increased. When weeds in the field are highly resistant, the dosage should also be appropriately increased. However, the pure medicinal dosage per acre should not exceed 9 grams, otherwise it will have adverse effects on the growth of wheat seedlings.
1. There is actually no big difference between the broad-spectrum herbicides Clodinafop-propargyl and me fenoxapropyl. Their herbicidal spectrum is basically the same. 20g of Maiji is very effective against Kanmainiang. In Japan, it is already very effective at Kanmainiang. , for wormwood, the dosage should be increased to 30g,Clodinafop-propargyl is slightly more effective in killing wormwood than oxazofop-propyl.
2. Low temperature resistance: Temperature has almost no effect on the effect of Clodinafop-propargyl-propargyl, but if the temperature is too low, the speed of grass death will be greatly reduced. Secondly,Clodinafop-propargyl is better resistant to rain erosion. Generally, we conservatively recommend that it takes 2 hours after the drug is administered, while it takes 4 hours for carboxypropyl-propyl.
3. Low-toxicity Clodinafop-propargyl is a professional herbicide for wheat. If farmers use it correctly, it will be difficult to cause any harm. Moreover, its mixability is also quite good. It can be used with bensulfuron-methyl, isopropuron, and fluroxypyr. The mixing effect is very good.
