How do you control weeds when growing lotus root? Which herbicide works better? We'd also like experienced growers to share their adviceDuring the growth of lotus root, especially in the early stage of shallow-water lotus root growth, the paddy field contains many weeds such as pondweed, needle spikerush, dwarf arrowhead, triangular bulrush, four-leaf clover fern, and black algae, which grow quickly and affect lotus root growth. Therefore, Zhongdiwang has compiled several weed control methods for lotus root fields, listed below for growers' reference.
Method one,Using manual inter-row cultivation and weeding, this is suitable for lotus root fields that are small or do not have a large area of weeds. The drawbacks are the heavy workload and the ease of stepping on and damaging the underground stem buds of the lotus root.
Method two,Using 50% Weiluosheng emulsifiable concentrate, when the standing leaves of the lotus root grow 30 cm above the water surface, take 100 milliliters of the pesticide, first mix it with 5 kilograms of urea, then add 5 kilograms of fine soil, mix thoroughly, and broadcast it into the field when the dew has dried. When applying, keep the water depth in the lotus field at 7-10 cm, and maintain the water layer for more than a week after application. The effect is good, and the residual effect period can reach more than 1 month.
Method three,Using 40 milliliters of 12.5% gallant or 35% quizalofop-p-ethyl, add 40-50 kilograms of water, mix thoroughly, and spray on the weed leaves when the dew is dry. After 4 days, the effect on killing grass-family weeds at the 3-4 leaf stage is significant.
