If something is not eating your plants,

then your garden is not part of the ecosytem.”


Pests are a hindrance in agriculture and hence most farmers opt for using pesticides to eradicate them from their farms. But using this pesticides bring a lot of damage to our health, environment and also the soil and in most cases it does not solve the problem but only bring harm.

Research has been done on better Ecological Pest Management techniques you can use for your farm to repel pests in your farm rather than killing. These techniques are economically and Environmental friendly and are locally available. I’ll share some common remedies you can use at your farm that you can use.

Organic Pesticides
