1. Yu Nongle (Nicosulfuron): Broad-spectrum herbicides are effective against grassy weeds and broad-leaved weeds, with good weed control and safe corn. However, it should be noted that Yunongle is not safe for the Denghai series of corn varieties, and is prone to injury. If the cultivated corn varieties belong to the Denghai system, they cannot choose Yunong's music; in addition, Yunongle sticks to sticky corn, Special maize such as sweet corn and popcorn is not safe and cannot be used.
2. Atrazine (Atrazine): A broad-spectrum herbicide is effective against grassy weeds and broad-leaved weeds. It is effective against weeds and is safe for corn. It is used for pre-emergence soil closure and post-emergence shoot treatment. Can be used. However, the effect of post-emergence seedlings on grass weeds is somewhat less effective and has a greater effect on broad-leaved weeds.
3, with the farmer (octyl bromide benzene sunny) to prevent broad-leaved weed herbicides, weeding effect is good, corn safety. Need to be mixed with herbicides to control grass weeds.
4,2,4-D Butyl Ester: Herbicides that prevent broad-leaved weeds have good herbicidal effect, but different corn varieties have different susceptibility to them. In recent years, phytotoxicity often occurs after production, and the symptoms of pesticide injury It is often shown later in the corn growth period that the "gun shank" of the corn is the symptom of 2,4-D-butyl phthalate. The "gun shank" is not able to form a spike, resulting in an outbreak of a strain. Therefore, 2,4-D-butyl ester should be used with caution, and conventional maize varieties cultivated in large quantities in production can be used post-emergence, but the amount of drugs to be controlled must not be used in excess; unfamiliar, not large areas for production For corn varieties, 2,4-D-butyl ester is not recommended after seedling emergence.
It is recommended to mix combinations:
1, Yu Nong Lok mixed with Atrazine: two agents were used to recommend the amount of 1/2 or 2/3, are mixed with the current use.
2, Yu Nong happy, mixed farmer, mixed 2,4-D-butyl ester: recommended for use in conventional corn fields. The recommended amount of jade farmland and farm land use is 1/2, and 1,2-dibutyl butyl ester is 1/3 of the recommended amount.
