Scope of Use for MCPA-Sodium
1. MCPA-Sodium is often compounded with other ingredients as a herbicide. It is primarily used to control annual weeds such as barnyard grass, pondweed, needle spikerush, water chestnut, monochoria, arrowhead, difformed galingale, and ammannia.
2. When applying herbicides, soil moisture must be ensured. The efficacy of herbicides is related to soil temperature and humidity-generally, higher humidity leads to better results by facilitating the absorption of the chemical. Dosage must be strictly controlled, as excessive application should be avoided. MCPA-Sodium is a phenoxyacetic acid-based selective hormone-type herbicide, and overuse can easily lead to herbicide resistance.
3. In recent years, weeds have developed stronger resistance. To prevent excessive water loss, many weeds appear stunted and grayish-white but are actually mature. These weeds are often covered with fine white hairs, which reduce water evaporation and cause the herbicide solution to remain on the surface rather than being absorbed. Therefore, during periods of high temperature and drought, the volume of spray solution must be increased regardless of the herbicide used; otherwise, efficacy will be compromised.
Residual Effects of MCPA-Sodium on Subsequent Crops
1. MCPA is highly sensitive to seedlings of subsequent gramineous crops. Weeds develop increasing resistance during the 3-4 leaf stage, with peak resistance at the tillering stage, but sensitivity rises again during panicle differentiation. Efficacy significantly decreases when temperatures fall below 18°C, and the herbicide is ineffective against weeds that have not yet emerged.
2. When applying MCPA-Sodium herbicide, spray equipment must be used exclusively to avoid cross-contamination and subsequent crop damage due to improper cleaning. Depending on local weed resistance, MCPA-Sodium can be mixed with other herbicides in appropriate ratios to enhance efficacy while minimizing phytotoxicity. Sensitive growth stages must be avoided, and dosage must be carefully controlled to prevent uneven spraying and excessive concentration, which can lead to herbicide damage.
3. The timing of application is critical-applying too early or too late reduces effectiveness. The optimal application period for MCPA-Sodium is when corn reaches the 3-5 leaf stage. If applied too early, weeds may have just emerged with minimal leaf surface area, reducing herbicide absorption. If applied too late, although leaf coverage increases, weed resistance also becomes stronger.
