Herbs to use as organic pesticides on your crops and how to use them

Organic farming, the growing of crops without synthetic chemicals, is one of the best agricultural practices as it ensures the production of chemical-free food products while conserving the environment.

The key principles of organic farming include boosting soil health naturally, minimizing pollution, and ensuring farm animals’ health.

Some of the popular organic farming methods include Compost and natural fertilizers, Crop rotation, natural pest control, green manures, and cover crops.

Organic Pest Control 

Organic pest control is the use of natural methods and substances to manage and eliminate pests, rather than relying on synthetic chemicals.

The practice reduces the exposure to harmful chemicals, ensuring that the produce is safer for consumption.

Additionally, farmers and agricultural workers are less exposed to toxic substances, leading to better occupational health

Home-made organic pesticides should always be sprayed on crops during the cool part of the day (mornings or late afternoons) to avoid burning of the crops.
