Plants, like humans, sometimes get sick because of the activities of pathogens. When crops are diseased, their growth vigor will be severely damaged, leading to tremendous yield loss. To cure plant disease, farmers have been relying on synthetic pesticides for centuries; but the over-use of synthetic pesticides has caused pest resistance and serious environmental issues. To overcome this dilemma, companies like Terramera Inc. have been developing alternative powerful pest-managing products, namely biopesticides, which are eco-friendly bioactive agents derived from natural resources.
