How Field Looked As They Applied Herbicide For Beans

How Beans Field Looked Like After Herbicide was Used

Mode of Action of Beansclean 480 SL Herbicide
- Bentazone is a selective post-emergence herbicide.
- It kills all weeds and plants that have germinated and have come into contact with it except beans.
- For the herbicide to be effective, you must spray the weeds when they are still young.
- The weeds should be at the 3-4 leaves stage for this herbicide to effectively kill them.
- 3 days after we finished spraying our bean farm, I noted some older weeds are resistant to this herbicide.
- That’s why the manufacturer insists that you spray the weeds when they are still young.
- Another thing I noticed, it slightly injured the bean crop. As shown in the photo below.
- I expect the beans to overcome this injury and continue growing normally.

Slight Burning Injury Caused By Bentazone On Beans.

The Bean Farm 1 Month Later after Using Beansclean Herbicide:
From the photo, you can see that Bentazone is very effective in controlling weeds in beans.
The field is very clean, and it has very few weeds in it.

Why is proper weed control important?
Weed management is extremely important because;
- Weeds greatly reduce crop yield as well as its general performance.
- They harbor pests and diseases.
- They directly compete with plants for growth factors like sunlight, water, nutrients, space. This makes the plants weak and susceptible to attack by pathogens.
- Some are parasitic, others are harmful when eaten by livestock and humans.
- Generally, plants in the wrong places look ugly.
- Some weeds can damage the crop by producing toxic substances
- They cause harvesting problems, especially those that develop late in the crop season
Â
Â
What is the benefit of early/timely weed control?
Weed control is critical early in the season because;
- It eliminates competition for light, nutrients, and moisture, giving the crop the opportunity to establish well.
- It protects the palatability and nutritional potential of the crop
- It substantially curtails opportunities for pests’ establishment in the crop
- Young weeds are easier to control, e.g., they absorb and translocate herbicides better
- Weeding can be less effective in times of drought stress, which mostly occurs at later dates of the season
