Herbicide For Beans In Kenya, USA & World: Weed Management In Beans

Herbicide to Use On Fallow Land in Preparation for Bean Planting.

The land I leased was fallow.

It was INFESTED with the feared couch grass.

“Plowing the land as it is would cause future weeding problems.” I reasoned.

Why?

Killing couchgrass by plowing is very difficult.

Some of the grass stolon would be buried in the plowing process.

That would be like replanting the grass again.

In this case there was ONE solution.

“Spray ROUNDUP on the grass before doing any plowing!”

Roundup (also known as glyphosate a broad spectrum herbicide), was the best herbicide to use for this case.

It kills ALL the plants including weeds that it has been sprayed on.

By doing this, all the weeds and unwanted plants on the fallow field, first turned yellow, then brown and finally were Completely DEAD.

Two weeks later (after spraying roundup) I confidently plowed the land, knowing all the couchgrass was dead!

Herbicide to use After Beans Have Germinated:

This is where many bean farmers find themselves at the crossroad.

They don’t know which herbicide to use on their beans.

The good news is, “they don’t need to be in that confusion anymore.”

All they need to do is use an herbicide known as Bentazone 480g/l.

In Kenya, this herbicide is sold under the brand name “BEANSCLEAN 480SL”

Here below is a photo showing the herbicide:

How to use Bentazone/ BEANSCLEAN 480 SL

This herbicide is fairly easy to use.

If you intend to use a knapsack sprayer,

• Fill your Knapsack up to the 15-liter mark with water
• Add 200 ml of Beansclean in the 15 liters of water.
• Add a suitable sticker.
• Top up with water the remaining space until you reach the 20-liter mark.
• Agitate the tank using a stick or suitable material.
• Close the lid and the herbicide is ready to use.
• Spray it on actively growing weeds while ensuring all the weeds come into contact with the herbicide.

My friend and I did this, and I found that we used 2 hours to finish spraying one acre.

Mode of Action of Bentazone/BEANSCLEAN 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 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 in the next page.

I expect the beans to overcome this injury and continue growing normally.

Tools you Need To Apply Bentazone

Without a knapsack sprayer, you CANNOT use herbicides on your farm.

Of course a knapsack is an additional cost but it is absolutely necessary if you want to save time when farming.

When I was applying the bentazone as explained above, I was with one other person. It took us 3 hours to weed 1 acre of land.

If we were using jembes, I know it would have taken us days!

Just imagine the time savings by using a Knapsack and a herbicide!
