The natural reaction for most of us is to immediately use chemical pesticides to eliminate these &quot;enemies.&quot; However, the price often comes from depleted soil, the disappearance of beneficial organisms, and, most importantly, health risks for your family.

When the soil is healthy, plants synthesize thick layers of cutin on their leaf surfaces and natural resistance compounds within their sap.
