A pesticide was created from beer waste and manure: it does not harm nature and humans

Researchers are now striving to reduce waste from the agricultural industry and reduce

the amount of harmful chemicals used through the use of organic by-products.

In a new study, institute researchersNaicker's agricultural research and development project in Spain used the by-product of rapeseed cake and brewer's bagasse (waste beer grain), and fresh cow manure, to use as a potential method for soil disinfection, maintaining healthy soil microorganisms and increasing crop yields.

Both components have a high nitrogen content:it promotes the activation of beneficial microorganisms in the soil. This helps break down organic matter such as manure, as well as kill nematodes and other parasites that damage crops.

The main problem that the new one is fighting againstpesticide —nematodes. This is a type of common soil parasite that burrows into the root tissue of a plant to lay eggs, this activity causing the formation of gall or nodule-like tumors on the root. 

To disinfect the soil and reduce populationsnematodes, the authors added a new pesticide to the soil as a potential organic treatment. After the first crop treatment, the researchers found a significant reduction in irritation on the plant roots. As a result, there was an increase in yield by approximately 15% compared to control plots after a year.
