Characteristics of secondary weed growth

, : Characteristics of secondary weed growth. Sakharnaya Svekla: Proizvodstvo i Pererabotka ( 3): 18-20

A study was made in the Kiev region of the USSR of the total numbers and weights of a second flush of weeds accumulating in sugar beet. Weeds were removed manually for periods of 30-170 days after emergence of the crop. In 1 of 2 variants, pre- and post-emergence herbicide treatments were carried out, while the other received no treatment. Numbers and weights of weeds were found to be inversely related to the length of the weed-free period.
