Without going into the depths of controversy, chemicals are a necessary evil for many of us. Large collections held by individuals often require certain measures to ensure survival. After losing Worsleya and Pamianthe to bulb fly, my mindset shifted to more regular applications of conventional chemicals. I use pesticides. I use them carefully. The first step with pesticide use is to read the instructions, the second step is to read them again. Read them before each use. Study them between uses. The more you understand the chemical, the more effective you will be with its application. Be familiar with chemical rotation. It's not as simple as to throw down a bit of oily soap and expect your troubles to vanish. Organic compounds can be excellent resources, but sometimes conventional treatments are less toxic and safer to apply. This is a very complex subject and broad, definitive statements should be avoided. We must allow individuals to make individual decisions.
