Product Description Herbicide Combination Bromoxynil 20% + MCPA-sodium 20% WPProduct DescriptionBromoxynil is a selective herbicide with weed-inhibiting activity. Bromoxynil is effective in controlling broadleaf weeds and is widely used in field management of crops such as wheat and barley. Bromoxynil achieves its weed-killing effect by interfering with plant photosynthesis and water absorption.MCPA is a selective hormonal herbicide. Its mode of action is similar to that of 2,4-D. However, its volatility and action speed are lower than those of 2,4-D butyl ester emulsifiable concentrate, making it safer to use in cold rice-growing regions compared to 2,4-D. Gramineous plants are highly sensitive during the seedling stage, and resistance gradually increases after the three to four-leaf stage, peaking in mid-tillering. Sensitivity rises again during the panicle differentiation stage; thus, it is advisable to apply the herbicide at the end of the tillering stage in rice. MCPA is suitable for controlling speargrass, duckweed, water plantain, and other broadleaf weeds in rice, wheat, and other dryland crops.Application of Bromoxynil 1.Mainly used in cereals, flax, garlic, corn, onions, sorghum, etc., for post-emergence control of broadleaf weeds at the seedling stage.2.A selective post-emergence contact herbicide for foliar application. The herbicide is absorbed through the leaves with limited translocation within the plant. It rapidly causes plant tissue necrosis by inhibiting various processes of photosynthesis. Primarily used in wheat fields, corn, sorghum, and dryland flax to control broadleaf weeds such as Polygonum, Chenopodium, Amaranthus, Silene, Solanum, Xanthium, Salsola, Lithospermum, Convolvulus, and Fallopia.3.For wheat: Apply at the 3-5 leaf stage of wheat when broadleaf weeds have fully emerged but are still before the 4-leaf stage. Use 15-25.5 mL of 22.5% EC per 100 m2, diluted in 4.5 kg of water for uniform spraying, achieving over 90% control efficacy.4.Bromoxynil herbicide can also significantly increase crop yields by 10%-60%. The recommended application rate is 15 mL/100 m2.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 Crops1. 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.
