What weeds can bentazon herbicide control? On which crops can bentazon herbicide be used? We also ask knowledgeable netizens to help explainBentazon herbicide can generally be used on soybean, peanut, wheat, rice, corn, broad bean, kidney bean, pea, sugarcane, onion, sweet potato, potato, tea plantation, flax, alfalfa, mint, astragalus, perilla, turf, and so on. Therefore, Zhongdi Network has compiled the herbicidal principle and methods of use of bentazon herbicide, listed in detail below for netizens' reference.
Herbicidal principle of bentazon herbicide:
Bentazon is a highly selective seedling herbicide with contact and systemic translocation activity that inhibits photosynthesis. When used in dryland, it is mainly absorbed through the stems and leaves of weed seedlings; when used in paddy fields, it is absorbed through the roots and stems and leaves, inhibiting the photosynthesis and water metabolism of weeds, causing the weeds to starve to death. Bentazon herbicide can control sedges and broadleaf weeds, and is ineffective against grass weeds.
Weeds that bentazon herbicide can control:
Dryland weeds:Cocklebur, redroot pigweed, livid amaranth, spiny amaranth, Artemisia species, creeping thistle, giant thistle, beggarticks, Spanish needles, Persicaria lapathifolia, Persicaria orientale, Polygonum nodosum, purslane, wild watermelon seedling, cleavers, sunflower, Jerusalem artichoke, wild radish, Russian thistle, prickly sida, sow thistle, chickweed, datura, goosefoot, small goosefoot, black nightshade, dayflower (good effect at the 1-2 leaf stage, effect declines markedly after the 3-leaf stage), ragweed, shepherd's purse, field pennycress, Convolvulus species, mustard, velvetleaf, wild mustard, Brassica species, and many other broadleaf weeds.
Paddy field weeds:Monochoria vaginalis, Monochoria korsakowii, white water star anise, Monochoria vaginalis, Eleocharis yokoscensis, Scirpus juncoides, Cyperus difformis, Scirpus triqueter, beggarticks, arrowhead, Alisma orientale, Cyperus serotinus, Cyperus compactus, dayflower, etc.
Methods of use of bentazon herbicide
1. Use in paddy fields:20-30 days after rice transplanting, or 30-40 days after sowing in direct-seeded fields, when weeds grow to the 3-5 leaf stage, use 64-96 grams of active ingredient per mu, mixed with 30 liters of water. Before application, drain the field water so that all weeds are exposed above the water surface; choose a hot, windless, sunny day to spray; spray the solution evenly on the weed stems and leaves; 1-2 days after spraying, irrigate the field again. The control effect on Cyperaceae weeds and broadleaf weeds is remarkable, but it is ineffective against barnyardgrass.
2. Use on soybean:The suitable application period is when soybean grows to 1-3 compound leaves and weeds are at the 3-4 leaf stage. Use 48-96 grams of active ingredient per mu, mixed with 30-40 kg of water. Spray with a sprayer as a post-emergence stem and leaf treatment. It can control broadleaf weeds and weeds such as cocklebur, amaranth, Polygonum, Russian thistle, cleavers, vetch, and rice flatsedge in soybean fields, but it is ineffective against barnyardgrass.
3. Use on peanut:At the 2-5 leaf stage of peanut, use 133-200 milliliters of liquid per mu (64-96 grams of active ingredient), mixed with 30 liters of water for stem and leaf treatment. It can control broadleaf weeds and sedges such as cocklebur, Polygonum, purslane, and yellow nutsedge.
Precautions for bentazon herbicide:
Precautions one:High temperature and light are conducive to the efficacy of bentazon herbicide, so it should be used in sunny and warm weather. If heavy rain falls within 8 hours after application, the efficacy will be affected, and a supplementary spray is needed.
Precautions two:If the paddy field leaks water, it is not suitable for use.
Precautions three:Cotton and vegetables are sensitive to bentazon herbicide, so contact should be avoided.
Precautions four:Because bentazon herbicide mainly acts by contact, the weed stems and leaves need to be fully wetted when spraying.
