In China, the resistance of barnyard grass in a rice field has grown to a new high. The occurrence of high resistant barnyard grass is increasing, and in more regions, which brings a severe challenge to rice growers. Farmers have had to switch to transplanting because of the difficulty in controlling and removing the resistant barnyard grass in a direct seeding rice field, resulting in higher costs due to land preparation and manual work.


The usually used herbicide in a rice field is, for example, quinclorac, which is a selective special-effect herbicide for the control of barnyard grass in a rice field. If it is applied too early, it may cause phytotoxicity, while high temperatures may also cause phytotoxicity in the seedlings. In addition, with the long service of quinclorac and intentional overuse on some occasions, barnyard grass becomes resistant. The other herbicide, metamifop, can prevent and control a large variety of annual weeds such as crabgrass, barnyard grass, moleplant seed and eleusine indica, but its efficacy may decrease under high temperature. In some regions, growers say that metamifop has little effect on the control of eleusine indica.


Saidan, released by KingAgroot to market in 2021, can effectively control various resistant barnyard grass. Its control is more stable under high temperature than a conventional product, which is more dependable. Saidan contains a new patented compound, Tripyrasulfone, which is a mixture of two compounds of different action mechanism, formulated in perfect proportion, being systemic and with contact toxicity.


A test in Nanchang and Jiangxi revealed Saidan being applied in contrast to cyhalofop-butyl + metamifop + hormones in the same field. After seven days of application, it turned out that the effects of the two are very different, where Saidan appears superior. In Jiangxi, Zhejiang, Anhui and Hubei provinces, Saidan turned out to be very effective against barnyard grass. Hubei’s Gong’an County is a typical area affected by resistant barnyard grass in a rice field, where after five days of application of Saidan, barnyard grass dried up and rotted in water. As such, the product is highly recommended by farmers. In Wucheng County of Zhejiang Province, Saidan was sprayed by UAV for control of resistant barnyard grass. Seven days after the aerial application, resistant barnyard grass all died, while the rice was safe. With the use of Saidan, weed control efficiency is much elevated.
