Weed control is crucial for achieving a good soybean yield. Weeds, pests, and diseases are some of the main factors that can cause damage to soybean crops, but weeds are the most damaging. The outbreak of weeds can lead to a loss of 20 to 50 percent in soybean crops. It is important to keep soybean crops weed-free for 45 to 50 days after sowing to minimize weed damage.
Weeding in soybean crops should be carried out at regular intervals. The first weeding should be done after 20-25 days, and the second weeding after 40-45 days of planting the crop. For chemical control, it is recommended to spray Penzola 32 (Pendimethalin 30% + Imazethapyr 2%) at a rate of 1 liter per acre mixed with 200 liters of water within 72 hours of sowing.
Note: To achieve better results, it is important to ensure adequate soil moisture when using the weed killer, and it is advisable to use a flat fan nozzle.
