Tribenuron-Methyl, en meget effektiv selektiv systemisk herbicid efter opdræt, har spillet en afgørende rolle i landbrugsstyring siden dens udvikling og lancering af Dupont (USA) i 1980'erne . som et sulfonylurea herbicid for hvedefelter, det skiller sig ud for sine unikke egenskaber . i 1995, det blev officielt registreret til hvede, der er tildelt en, der er tildelt et, der beviser en et nyt, at et nyt, der er tildelt et, der er tildelt et nyt, der er tilmeldt et nyt, at det er tilmeldt, at et nyt nyt nyt nyt nyt nyt nyt til landbrugsproduktion .
Handlingsmåde
Tribenuron-methyl achieves herbicidal effects by inhibiting the activity of acetolactate synthase (ALS) in weeds. When ALS enzyme activity is suppressed, the synthesis of branched-chain amino acids in weeds is significantly reduced, thereby hindering protein synthesis. Due to insufficient protein synthesis, the growth and development of ukrudt påvirkes hårdt .
After absorbing tribenuron-methyl, the herbicide is translocated within the weed, first affecting the growing points and causing necrosis. Meanwhile, the veins of the weed lose their green color, disabling the leaves from performing photosynthesis normally and depriving the plant of essential energy and substances. These effects further inhibit weed growth, eventually leading to the death of the entire plante og nå målet med ukrudtskontrol .

2. Kontrolmål:
This product is mainly used to control annual broad - leaved weeds, such as Descurainia sophia, Capsella bursa - pastoris, Cardamine hirsuta, Lithospermum arvense, Chenopodium album, Amaranthus retroflexus, etc., which show significant response to tribenuron - methyl. Meanwhile, it also has certain Kontroleffekter på ukrudt som Kochia Scoparia, Stellaria Media, Polygonum, Galium Aparine osv. . Dog ukrudt såsom Cirsium Arvense, Fallopia Convolvulus, Convolvulus arvensis, Euphorbia Helioscopia viser ingen åbenlys reaktion til tribenuron -methyl, og gramine weeds som Avneed Avena Fatua, Alopecurus Aequalis, Bromus japonicus, Aegilops Tauschii er ineffektive mod dette produkt .
Applikationsmetoder
1. Common formulations of tribenuron-methyl include 10% wettable powder (WP) and 75% water-dispersible granules (WDG). Taking 10% tribenuron-methyl WP as an example, the dosage is typically 10–20 grams per mu, mixed with 15–30 kilograms of water, and then evenly sprayed onto the stængler og blade af ukrudt .
2. For mindre ukrudt kan lave doser opnå gode kontroleffekter ., hvis ukrudtet er større, kræves højere doser til behandling .
Forholdsregler
(1) Since the soil residual period of tribenuron-methyl is about 60 days, special caution is needed when planting sensitive crops such as peanuts and potatoes in the subsequent rotation. For winter wheat fields applied with tribenuron-methyl, planting peanuts in the subsequent rotation is strictly prohibited.
