carfentrazone, also known as Funong, Mirex, triadimefon-ethyl and carfentrazone-ethyl, is a triazolinone herbicide developed by FMC.

It is a great help to agriculture and a helper to relieve weeding for farmers' friends.

So, do you know the scope of use of carfentrazone? What are the precautions for using carfentrazone? Let's take a look at it.

application scope of carfentrazone-ethyl at present, carfentrazone-ethyl preparation in China is mainly used in wheat fields, paddy fields, sugarcane fields, wheat fields, corn fields, lawns, etc. At the same time, it can be compounded with glyphosate, which has outstanding effects on some resistant malignant broad-leaved weeds and sedges, and its application is very extensive.

the application of carfentrazone on applicable crops: it has a good killing effect on most broad-leaved weeds in wheat fields; It can control the whole growth period of barley from being harmed by broad-leaved weeds, and the weeding speed is fast and the yield is significantly increased; Generally, it is used only after the 4-leaf stage of rice, and mixed from the 5-leaf stage to the late tillering stage; Clomazone is suitable for corn field and has little effect on aerial rooting of corn. Clomazone is mainly used to control broad-leaved weeds in stem and leaf treatment of Gramineae lawn.

precautions for the use of carfentrazone 1. carfentrazone is an ultra-efficient herbicide, but wheat has strong resistance to carfentrazone, which can be used from the three-leaf stage to the jointing stage (usually from November to March of the following year). However, if the pesticide is not applied properly, yellow burn spots will appear on the leaves of wheat seedlings after application. If the dosage is large and the concentration is high, the burn spots will be large and the damage will be obvious.

therefore, the dosage must be accurate when applying the medicine, so that the medicine can be made into mother liquor and then added into the sprayer.

spraying should be uniform, and re-spraying is not allowed, so as not to cause serious phytotoxicity to crops.

2. Clomazone only has contact killing effect on weeds, and has no soil sealing effect, so it should be used as far as possible after most weeds in the field emerge.

3. Yellow spots will appear on the leaves of wheat after spraying from jointing stage to booting stage, but it will return to normal green one week after spraying without affecting the yield.

4. The medical machinery sprayed with metazolone should be thoroughly cleaned, so as to avoid pesticide residue and other crops.

Matters needing attention in mixing carfentrazone-ethyl with other herbicides in wheat field 1. When spraying carfentrazone-ethyl and its compound with tribenuron-methyl, 2-methyl-4-chlorine and bensulfuron-methyl, washing powder, silicone and other additives should not be added to the liquid medicine, otherwise it will easily cause phytotoxicity to crops.

2. It is not advisable to mix the drug containing carfentrazone-ethyl with the emulsifiable concentrate such as Xuma (fenoxaprop-p-ethyl), otherwise the dispersity of carfentrazone-ethyl in the liquid medicine may be affected. After spraying, the drug is unevenly distributed on the leaves, and the parts with more drugs are prone to phytotoxicity, but they can be used separately. For example, if one drug is applied one day and another drug is applied the next, there will be no phytotoxicity.

3. For the field where gramineous weeds and broad-leaved weeds are mixed, clomazone and its compound with tribenuron-methyl and bensulfuron-methyl can be mixed, and both kinds of weeds can be eliminated.
