Embodiment 1

[0018] Example 1: Indoor toxicity test of herbicidal composition on barnyardgrass.

[0019] Test method: The test is carried out under greenhouse conditions. A certain amount of soil is placed in a pot with a diameter of 13 cm, and the germinated seeds are sown in the pot to ensure that each pot has 30 seeds. The seeds are covered with sand and fine soil about 1 cm thick. , Add water from the bottom of the pot to keep the soil moist with a water content of 25-35%. When the weeds grow to the 3-4 leaf stage, keep 15 weeds in each pot and treat the stems and leaves, and spray water on the stems and leaves after the leaves are dry. Each treatment was repeated 4 times. Continue to cultivate under greenhouse conditions after the treatment with the chemical agent, weigh the fresh weight of the aboveground part 15 days after the treatment, and calculate the fresh weight control effect. Fresh weight inhibition rate / %=[(fresh weight of control weeds-fresh weight of treated weeds) / fres...

Abstract

The invention belongs to the field of pesticide compositions, and specifically provides a ternary weeding composition containing propyrisulfuron and application of the ternary weeding composition. Active ingredients of the ternary weeding composition are composed of propyrisulfuron, pyraclonil and beflubutamid in a weight proportion of (1-10) to (3-20) to (1-15). The ternary weeding composition containing the propyrisulfuron is used for controlling and eliminating rice field weeds, especially grass-family, broad-leaf and sedge weeds.

Description

technical field [0001] The invention belongs to the field of pesticide compositions, and in particular relates to a ternary herbicidal composition containing promasulfuron-methyl and an application thereof. Background technique [0002] At present, the control of weeds in paddy fields in my country is still dominated by chemical means, supplemented by measures such as artificial weeding or biological control. Therefore, how to select safe, efficient and long-lasting herbicides is particularly important to effectively control weeds and ensure high and stable yields of direct-seeding rice. [0003] Promethazone-methyl is a selective broad-spectrum sulfonylurea herbicide. After being absorbed by the roots, stems and leaves of weeds, it can inhibit the activity of acetolactate synthase and stop its growth until it dies. The agent was developed by Sumitomo Chemical Co., Ltd. in Japan. It obtained the original drug and product registration in my country in 2014, and carried out d...
