Control of Johnson grass in cotton rotations


, : Control of Johnson grass in cotton rotations. Zashchita Rastenii (11): 14-15

Recommendations on the control of Sorghum halepense in cotton grown in different rotations in Uzbekistan are given. In cotton/lucerne rotations S. halepense is best controlled by applying 40-50 kg Propinat ha before or after autumn ploughing and 5-6 litre Treflan before sowing cotton in spring. Treflan effectively controls annual grassy weeds and S. halepense seedlings emerging from the seeds.
