When it comes to soybean production, implementing effective weed control strategies is a crucial component to consider. Due to the presence of weeds, there can be a potential loss in the soybean yield, harvesting difficulties, and quality loss in crops. It is also crucial to know that certain weed species such as Pigweed and Lambsquarters, and more can make thousands of seeds from just a single plant causing a lot of weed seeds to be added to the soil bank.
Major problematic weeds in Soybean are Echinocloa colona, Digitaria sp., Dactyloctenium aegyptium, Cyperus iria, Alternanthera sp., Amaranthus viridis, Euphorbia hirta, and Commelina benghalensis, etc.
That’s why it is suggested to control the population of the majority of the weeds, especially the new ones before they hit their maturity. Studies suggest that weeds growing with soybean during the first three weeks do not reduce the yield under normal environmental conditions and it is advised to check the weed growth as soon as possible.
However, if it remains in the crop for 3 to 8 weeks post the emergence of Soybean, the weed can potentially reduce the yield as well as the quality of the crop. Additionally, weeds that emerge after 6 to 8 weeks are not likely to cause any reduction in the yield.
How To Effectively Control Weed in Soybean
One of the most effective ways to control weed in Soybean is to incorporate a weed management program. This may include crop rotation, cultural weed control practices, good crop production practices, and the use of the herbicide for soybean.
To make an effective weed control program, you need to be aware of the species that are present in the field and understand their biology. The most difficult to control weeds are the ones that emerge early with the crops.
You can consider using a seedbed during planting with the help of tillage or herbicides in no-till. Keep in mind that uncontrolled weeds can eat up all the moisture and nutrients, and even interfere with planting, making it difficult to control due to their advanced growth.
Using a combination of herbicide for soybean with different action modes will help you get a broader spectrum of control and inhibit the growth of herbicide-resistant weeds.
Dhanuka Agritech Limited is one of the top agrochemical manufacturers in india offers a wide range of products for weed control in Soybean , some of them are: Targa Super, Maxsoy, Dabooch, Sakura etc.
Bottom Line
All in all, it is evident how degrading weeds can be for beneficial Soybean crops and its yield. Fortunately, there is a myriad of ways to control weeds in these crops through various means like Chemical Control, Mechanical control, Intercultural operation and IWM.
