Can enfedipine beat millet?

Enfedipine is not suitable for beating millet, it has a certain inhibitory effect on the growth of most millet, if you want to hit millet, it is best to reduce the dose, or use other herbicides to beat millet.

I. the use of enoxetine

The highly selective internal absorption and conduction type stem and leaf treatment agent can be quickly absorbed by the stems and leaves of Gramineae weeds and transmitted to the apical and Internode meristem, resulting in cell division and destruction to death. It can be used in soybean, cotton, rape, peanut, potato, sugar beet, sunflower, flax and other crops and orchards to control barnyardgrass, wild oat, dogtail grass, Euphorbia angustifolia, Saxifraga, etc., but not to broad-leaved weeds. For example, to control weeds in soybean and cotton fields, spray water with 20% EC 10~20mL/100m2 and 8~15mL/100m2 respectively, or spray water with 5% EC 10~15mL/100m2.

Second, the production method of enoxetine.

1.ETO was prepared by addition of butene-2-aldehyde with ethanethiol under the catalysis of tertiary amine to form 3-ethylthiobutyraldehyde; methyl acetoacetate was hydrolyzed to form sodium acetoacetate; then 3-ethylthiobutyraldehyde reacted with sodium acetoacetate and 6-ethylthio-3-heptene-2-one (ETO) was synthesized at 20 ℃ with N-methylhexylamine as catalyst.

In the presence of sodium methoxide, 2.CDNA was prepared by Michael (Michel) addition with dimethyl malonate, followed by cyclization, hydrolysis and decarboxylation to give 5-[2-(ethylthio) propyl]-1 (CDNA).

3. The synthesis of DNA uses butyryl chloride as acylating agent for acylation. Because butyryl chloride is easy to be hydrolyzed, the reaction should be carried out in organic solvent and phase transfer catalyst should be used. The acylated products are rearranged under the catalysis of 4murine N-dimethylpyridine. The rearranged product was condensed with ethoxylamine to form oxime under the mild condition of 40 ~ 60 ℃, and dilute Heding was prepared in high yield.

When using chemicals, you must choose according to the growth of crops, and consult clearly before buying drugs, so as to avoid misuse and misuse.
