1. Weed control mechanism

Bentazone is a selective post - seedling herbicide. When used in dry field, it inhibits photosynthesis through osmotic conduction of plant leaves into chlorophyll. When used in paddy field, it can be permeated by plant foliage and absorbed by root system, which can be transmitted to stem and leaves, inhibit photosynthesis and water metabolism, and cause weed physiological dysfunction and death. After 8 to 16 weeks of application, the plant could be decomposed by microorganisms in soil.

2. Control object

Can control cleavers, chickweed, shepherd's purse, sorrel leaf smartweed, alisma, short water pack, water amaranth, hotaru rush, sedges, broken rice sedge, abutilon, ghost needle grass, xanthium sibiricum, purslane, duck plantar grass, quinoa, such as annual broadleaf weeds and sedge, invalid to gramineous weeds, for her mother-in-law, vetch, Armstrong, leaf mustard, thistle, alternanthera philoxeroides, water sedge, fly eye, salvinia natans ping, wild soybean, Tian Xuan iron flower, amaranth, dissolving and cracked leaf petunia control effect is poor.

3. Use technology

It can be used for weeding after seedling in rice, wheat, corn, soybean, peanut, onion, garlic and grass lawns.

①　Rice

It can be used for chemical weeding of various paddy fields. Usually about 7 days before the seedling in seedling bed, seedling slinging , plant transplanting field, direct seeding behind or 20 ~ 30 days after sowing, annual broadleaf grass, sedges 2 ~ 5 leaf stage, with 48% SL per mu 135 ~ 200 ml, 30 ~ 40 kg of water spray, when applying pesticide should be drained paddy, let the weeds all appear, medicine again water, 1 ~ 2 days after returning to normal water management.

②　Wheat

Before winter in wheat seedling 3 leaves, spring in wheat seedling tillering stage, broadleaved weeds 2 ~ 5 leaves, per mu with 48% SL 100 ~ 150 ml, 30 ~ 40 kg of water spray.

③　Soybean

The broad-leaved weeds after bean field seedling stage 2 ~ 5 leaves, per mu with 48% SL 100 ~ 200 ml, 30 ~ 40 kg of water spray. Perennial weeds such as aconite, small thistle and so on should be controlled by two application methods: 100 milliliters of 48% water agent should be used per mu, and 30 ~ 40 kg of water should be sprayed, and the weeds should be sprayed again once every 7 ~ 10 days when they grow new buds.
