The herbicide Efes is a contact agent for controlling annual dicotyledonous weeds in pea and soybean crops. The active ingredient of the product is bentazon at a concentration of 480 g/l. Efes effectively suppresses a wide range of weeds, including those resistant to 2,4-D and 2M-4X acid-based herbicides, such as Ambrosia artemisiifolia, Galinsoga parviflora, field mustard, and others. The mechanism of action of the herbicide is based on disrupting the function of the second photosynthetic system, leading to cessation of weed development and cell division.
The product is available as a soluble concentrate and supplied in plastic drums of 20 liters. Efes is characterized by high selectivity towards crop plants, allowing its use without harm to pea and soybean. The optimal timing for treating pea is the 5-6 leaf stage, and for soybean — 1-3 true leaves. The application rate varies depending on the crop and weed development stage: for pea, 3.0 L/ha is recommended, for soybean — from 1.5 to 3.0 L/ha. The working solution is applied at a volume of 200-400 L/ha.
Efes is characterized by high speed of action and prolonged protective effect. The efficacy of the product increases at air temperatures from +15 to +25 °C, making it especially useful in warm weather. The toxicity class of the herbicide is III (moderately toxic), requiring adherence to standard safety measures during application. Due to its properties, Efes is a reliable tool for protecting pea and soybean crops from a broad spectrum of dicotyledonous weeds.
