Why Should We Use Natural Pesticides for Plants


For any farmer or gardener, pesticide plays a crucial part in the growth of the plant and the yield of the products. Nowadays, going organic or going green has come into the limelight, and everyone should follow it as it is one of the ways to save the environment.

Some people think that going organic, no pesticides are utilized, but this isn’t the case. Pesticides are a crucial component of the growing process for farmers and gardeners because they help preserve and protect crops all year. That’s why farmers and gardeners should use pesticides, but these pesticides should be natural.

The main distinction between natural and conventional chemical pesticides is that organic pesticides use naturally occurring compounds rather than synthetically created ones. To cultivate healthy plants, organic gardeners first focus on enriching the soil with natural materials like well-rotted manure or homemade pesticides, organic Fertilizer, and “traditional” fertilizers like bone meal or fish blood and bone. Along with them, one should use natural pesticides too.

What are Natural Pesticides?

In simple words, natural pesticides are pesticides that can quickly decompose into the environment without damaging it. These pesticides are created using natural elements. Opting for these pesticides not only helps you in removing toxins from your food but also helps in the Environmental Management System. You can either get these natural pesticides from the market or even prepare them on your own using scratch items.

Why Should Everyone Use Natural Pesticides?

Food has become necessary and a business in the present world. To get high yields, most farmers use harmful chemical pesticides. These pesticides are very toxic with chemicals, can cause soil pollution, and can kill beneficial organisms like earthworms.

Exposure to synthetic pesticides will cause cardiovascular issues and several other health effects. That’s why everyone should opt for natural pesticides. Using biodegradable natural pesticides can prevent the harmful effects of non-biodegradable waste. Along with crops and gardening, you can also use these natural pesticides for indoor plants.

Numerous organic pesticides exist that have less influence on the environment and pose less risk because they are not created by chemical engineering. Organic pesticides provide several advantages over conventional pesticides, including a narrow target range, a slower mode of action, a brief persistence, low residue levels, and safety during application.

These qualities benefit both customers and the environment, but as with any product, you must use precaution and pay close attention to the timing and approach to management.
