Tribenuron-methyl, a highly efficient selective systemic post-emergence herbicide, has played a crucial role in farmland management since its development and launch by DuPont (USA) in the 1980s. As a sulfonylurea herbicide for wheat fields, it stands out for its unique properties. In 1995, it was officially registered in China, providing a Nova rešitev za kmetijsko proizvodnjo .
Način dejanja
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, Rast in razvoj plevela močno vplivata .
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 celotne rastline in doseganje cilja nadzora plevela .

2. Nadzorni cilji:
Ta izdelek se uporablja predvsem za nadzor letnega širokega plevela, kot so Descurainia Sophia, Capsella Bursa - Pastoris, Cardamine Hirsuta, Lithospermum Arvense, Chenopodium album, Amaranthus Retroflexus itd. Plevel, kot so Kochia Scoparia, Stellaria Media, Polygonum, Galium Aparin itd. Alopecurus aequalis, Bromus japonicus, aegilops tauschii niso učinkoviti proti temu izdelku .
Metode aplikacije
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 stebla in listi plevela .

Previdnostni ukrepi
(1) Ker je preostalo obdobje tal tribenuron-metil približno 60 dni, je potrebna posebna previdnost pri sajenju občutljivih pridelkov, kot so arašidi in krompir v naslednjem vrtenju . za zimska pšenična polja, ki se nanašajo na tribenoronsko-metil, je vgrajena {5 {5 {5 {5 {5 {
(2) Tribenuron-metil se večinoma uporablja za nadzor nastajajočih plevelov in ima slabo učinkovitost proti neizkoriščenim plevelom . izogibajte se razprševanju v močnih vetrovnih razmerah, da prepreči, da bi se herbicid raztopila na sosednje široke liste in povzročila fitotoksičnost .
(3) Tribenuron-metil je mogoče uporabiti samo enkrat na sezono pridelkov . odmerjanje je treba med nanosom strogo nadzorovati, za pripravo pa je treba sprejeti sekundarno metodo redčenja . po uporabi, mora biti razprševalna oprema temeljito očiščena, da se izognemo preostalim kemikalijam, ki vplivajo na druge krogle.
