Mechanism and characteristics of triazole mesotrione
Triazoloft is a brand-new HPPD inhibitor, which can cause weed death in three ways.
Cut off the energy conversion of photosynthesis
Cut off vitamin synthesis
Destroy the green protection of leaves
Characteristics of triadimefon:
It is a brand-new HPPD inhibitor, and it is the first time to apply HPPD inhibitor to the spraying treatment of stems and leaves after rice seedlings.
Can effectively solve the problems of Euphorbia Euphorbia resistance and barnyard grass resistance.
It has no cross-resistance with the current mainstream drugs, and can effectively solve the more complicated resistance problems of poinsettia and barnyard grass at present and in the future.
It can be mixed with a proper amount of 2- methyl bentazone to improve the control effect of broadleaf weeds and Cyperaceae weeds and improve the weeding efficiency of growers.
Yangtze valley: the daughter of resistance.
Ningxia: multi-resistant barnyard grass, barnyard grass, barnyard grass.
Northeast China: resistant to barnyard grass, barnyard grass and annual barnyard grass.
Time and dosage of pesticide application in the Yangtze River basin
Application period:
Direct seeding rice: after the three-leaf stage of japonica rice to before the jointing stage.
Indica rice No.4 is after leaf stage and before jointing stage (generally, it is 15~ 18 days after direct seeding of one season rice, and 10~ 12 days after middle and late rice).
Transplanting knife: after the water knife turns green completely, before jointing (about 7~ 10 days after transplanting)
Dosage:
300g+20g water shall not exceed 16 liter.
300g+20g flood control water shall not exceed 16L, and the recommended dosage per mu shall not exceed 375g+25g.
After the herbicide is out of control, the interval should be 5-7 days. After the weeds return to normal growth, this product can be used for auxiliary control.
Time and dosage of pesticide application in Ningxia rice region
Application period: after the heart stage (20 days after 1 6-water direct seeding) of two leaves of japonica rice No.2 to before jointing stage.
Dosage:
With the increase of leaf age, the dosage should be increased appropriately, but the dosage of knife should not exceed 450g and that of cypress should not exceed 30 g.
Select equipment with good spraying quality to spray this product.
Time and dosage of pesticide application in Northeast Island
Application period:
Direct seeding: after the 3-leaf stage of rice (generally 20 days after direct seeding) to before jointing stage.
Transplanting: rice seedlings are fully delayed until after jointing stage (generally, rice seedlings are delayed by 10- 15 days after transplanting, and the delay time can be extended to 15-20 days in case of cold weather).
