Herbicide Clodinafop-propargyl 95%TC Cas 105512-06-9

Clodinafop-propargyl is a post-emergence herbicide for cereals, which is mainly used for annual grass weeds. From clodinafop-propargyl being absorbed to weed death is relatively slow, generally takes a week. Small cereal crops do not have sufficient drug resistance, and special crop safeners are needed.

Clodinafop propargyl, chemical name 2-propynyl-(R)-2-[4-(5-chloro-3-fluoro-2-pyridyloxy)phenoxy]propionate, belongs to aryloxyphenoxypropionate Acid herbicide, clodinafop-propargyl is a post-emergent herbicide for grains, mainly used to control annual grass weeds such as wild oats, ryegrass, ryegrass and foxtail.

The herbicide is a chiral fluorine-containing phenoxycarboxylic acid herbicide, which is relatively stable in acidic medium and hydrolyzed in alkaline medium. Clodinafop-propargyl is an inhibitor of acetylidene coenzyme carboxylase, a systemic herbicide that is absorbedby the leaves and sheaths of plants, conducts in the phloem, accumulates in the meristems of plants, and inhibits acetylidene coenzyme carboxylase. Fatty acid synthesis stops, cell growth and division cannot proceed normally, membrane system and other lipid-containing structures are destroyed, and finally plant death is caused. From the absorption of clodinafil to the death of weeds is relatively slow, generally takes a week. When appliedalone, small-grain cereal crops do not have sufficient drug resistance, and special crop safeners are required.

Mechanism of action of clodinafop-propargyl

Clodinafop-propargyl is a systemic conductive herbicide. The drug is absorbed through the leaves and leaf sheaths of plants, conducts through the phloem, and accumulates in the meristems of plants. It inhibits acetyl-CoA carboxylase (ACCase), stops fatty acid synthesis, and cells The growth and division of the plant cannot be carried out normally, the lipid-containing structure such as the membrane system is destroyed, and finally the plant dies.

Features of clodinafop-propargyl

1. The broad-spectrum herbicide clodinafop-propargyl and fenoxaprop-p-ethyl are actually not very different, and the herbicidal spectrum is basically the same. 20g of wheat is very good for Mai Niang, and the effect of Japanese Mai Niang is already very ideal , the dose of fenugreek should be increased to 30g, and the effect of clodinafop-propargyl on saffron is slightly better than that of fenoxaprop-ethyl.

2. Low temperature resistance The temperature has almost no effect on the effect of clodinafop-propargyl, but the speed of dead grass will be greatly reduced if the temperature is too low. Secondly, clodinafop-propargyl has better resistance to rain erosion. Generally, we conservatively introduce that it takes 2 hours after the medicine, while fenoxaprop-ethyl takes 4 hours.

3. Low toxicity clodinafop-propargyl is a professional wheat herbicide. If the farmers use it correctly, it is basically difficult to cause any harm, and its compatibility is also quite good. It is compatible with tribenuron-methyl, isoproturon, and fluroxyfen Mixing works fine.

Properties of Clodinafop-propargyl

When used alone, clodinafopargyl is harmful to monocotyledonous crops, so a special safener has been developed. The ratio of the two preparations is 4:1. After mixing, the recommended dosage is twice the amount used to control wheat and weeds. Chemicalbook Safety. Within 1 to 2 days of using this agent, the sensitive plants will stop growing, and the young leaves will die first, and then the old leaves will also turn green and die; when the dose is enough to kill, the leaves will gradually deform and the leaves will be out of balance.

Advantages of clodinafop-propargyl

Because clodinafop-propargyl has low phytotoxicity to cereal crops such as wheat, in order to improve its safety to crops, clodinafop-propargyl is usually mixed with the safener cloclodin-propargyl. The addition of clodinafop-propargyl can ensure that grains such as wheat, rye and triticale have excellent tolerance to clodinafop-propargyl. The compounding ratio of clodinafop-propargyl and clodinafop-propargyl is usually 4:1, Topik (top) is the product under this ratio, which is 240 g/L clodinafop-propargyl emulsifiable concentrate, in which 60 g/L cloclodin-clodin-propargyl is added .

The safety of clodinafop-propargyl to wheat is relatively good, and the requirement of wheat seedling age is not high for pesticide application. It is generally required to apply when the wheat is at the 2-leaf and 1-heart stage and before jointing, when the weeds are basically out and at the 2-4 leaf stage. After the grass age increases, the dosage should be increased appropriately, and the dosage should also be increased appropriately when the weeds in the field are more resistant. However, the amount of pure medicine per mu should not exceed 9 grams, otherwise it will cause adverse effects on the growth of wheat seedlings.

How to use clodinafop-propargyl

1. Weeding in orchards, mulberry gardens, etc. Use 0.5-1 kg of 10% water spray per mu to control annual weeds, and use 1-1.5 kg of 10% water spray per mu to control perennial weeds. Use 20-30 kg of water, and spray directional spray on weed stems and leaves.

2. Weeding in farmland Before sowing in stubble in farmland, prevent and control the weeds that have grown in the field. The dosage can refer to weeding in orchard. For cotton growth period medication, directional spray with hood spray is required. Use 0.5-0.75 kg of 10% water agent per mu, and 20-30 kg of water.

3. Weeding in leisure land, fields and roadsides: At the 4-6 leaf stage of weeds, use 0.5-1 kg of 10% water agent per mu, add 100 ml of diesel oil, and spray 20-30 kg of water on weeds.

4. For some vicious weeds, such as Cyperus cyperus and reed, 200 grams of additives can be added per mu of land, and the weeding effect is good.

Precautions for clodinafop-propargyl

1. Clodinafop-propargyl is a non-toxic herbicide, so do not contaminate crops when spraying to avoid phytotoxicity.

2. For perennial vicious weeds, such as Imperata Imperata, Cyperus Cyperi, etc., apply the medicine one month after the first application to achieve the ideal control effect.

3. Adding an appropriate amount of diesel or washing powder to the liquid medicine can improve the efficacy of the medicine.

4. In sunny days and high temperature, the drug effect is good, and it should be re-sprayed in case of rain within 4-6 hours after spraying.

5. Clodinafop-propargyl is acidic, and plastic containers should be used as much as possible for storage and use.

6. The spraying equipment should be cleaned repeatedly.

7. When the package is damaged, it may become damp and agglomerate under high humidity, and crystals may also precipitate during low-temperature storage. When using it, the container should be fully shaken to dissolve the crystals to ensure the efficacy of the medicine.
