An article was published online in Wiley Online Library, where they have researched to figure out whether weed killers can kill Nematodes or not.

They have used a weed killer to see how various feeding groups react after applying it. The result was not impressive.

The weed killer reduced the richness of two feeding groups (predators and fungivores) But increased the richness of three two feeding groups (omnivores, plant parasites, and bacterivores).

As a result of weed killer application, nematode richness grew further. So, the weed killer didn’t give effective results to deal with them.

So, why the weed killer reduced the abundance of few feeding groups while increased other feeding groups? The weed killer killed many predators and fungivores because the application of herbicides negatively affects both fungivores and predators.

On the other hand, the abundance of other feeding groups increased because these groups received food resources from the weed killers.

After turning up the soil, water them slightly. Use a hosepipe to sprinkle water and make them dampened but not moist.

The solarized soil will become hotter due to this. Additionally, it will increase the huge amount of nematodes. The solarization process won’t be effective if your garden soil is excessively dry or powdery.

Another thing you can do is let garden soil drenched properly from rain and start the work the next day.

Now collect a plastic sheet to cover the whole soil area. Make sure the sheet is clear to be visible from inside to outside.

After covering the whole soil area with the plastic sheet, use additional soil to seal the entire region. Make sure to close the gap, and all sides of the sheet are secured by using the excess soil properly.

Retaining the moisture of the soil is what it does as there is no airflow. Also, the sunlight will directly reach the area, and the heat won’t come out. It will increase the temperature inside under plastic sheet gradually.

Step 5— Solarizing Procedure

Solarizing Procedure

So, you have done everything. Now, lets the sunlight reach properly on the soil and trap the nematodes.

So, how many weeks do you need to keep them in that condition?

An increase of 2-3 degrees of heat is not enough to kill nematodes. The temperature needs to reach at least 35°C (95°F) to kill nematodes.

According to most experts, a minimum of 6 weeks is necessary to raise the heat at this level. One rule of thumb is working on it during the summer season since the temperature is higher during this season than in other seasons.

During the six weeks of the solarizing procedure, make the plastic sheet is properly covered. Check each side of the sheet to ensure no uncovered.

Step 6—Removing The Plastic Sheet

After six weeks of the solarizing procedure, finally, you can remove the plastic sheet. Recycle the plastic. Now, your garden soil is completely ready to grow new plants. That’s it!

You should dig the soil more than 7-8 inches because the solarization process only worked for the top of 7-8 inches of soil.
