What You Need To Know About Pesticides

 There are a lot of opinions about

pesticides out there. There is also a lot of information about a lot of different kinds of pesticides. Just walking into the pesticide aisle at a hardware store can be daunting. If you have a problem with a pest and don't know what to do, here is some basic information you need to know. 

First, the best thing you can do to fight any problem is grow happy healthy plants. A tomato growing in full sun with good soil and consistent moisture is going to do much better at fighting off any problems then the same plant in partial shade and bad dirt. So be sure you know how to make your plants desirable. 

Second, be sure you accurately diagnose the problem. You can dump all the insecticide in the world on your plant but if the problem is fungal, then it's not going to solve your problem. In the meanwhile, you've wasted your time, money and energy and probably killed a lot of nice pollinators. Identifying a problem can be tricky. You can do some research on line or contact your county extension office for help. 

Third, use the least toxic solution possible to solve your problem. All pesticides have a trade off. Organic and narrow spectrum treatments will have a lot less side issues than more toxic options. For instance, you can use BT, an organic bacteria, to kill caterpillars and it won't hurt pollinators like a more conventional pesticide might. Assuming, of course, that caterpillars are your problem.

Fourth, if you buy pesticide, you must read and follow the instructions!!! I know it's not fun but absolutely necessary. If you put too much on, it can be toxic and damage plants. If it's too weak, it might not work. So be sure to read the instructions and follow them carefully. 

Fifth, 95% off all pesticide injury (to people) is from skin damage on hands and arms. So, if you wear safely gloves and a long sleeve shirt, your in pretty good shape. However, wear eye protection if the chemical in use recommends it. Don't skimp on safety. 

Finally, be a good observer. Is the pesticide working well? Are there bad side effects? Keep an eye on your plants and always be learning.
