Is Sevin A Good General Purpose Insecticide?
I've noticed tiny pin holes in the leaves of my bell peppers, egg plants, ground cherries and cantaloupe. My neighbor told me that he uses a product called Sevin that comes in a spray bottle ready to use. Said he's been using it for years and it works quite well for him. I guess my question is: would this be a good general purpose insecticide for use in my vegetable garden? Rich from PA |

I guess my question is: would this be a good general purpose insecticide for use in my vegetable garden? Rich from PA Sevin is the trade name of an insecticide called carbaryl. It is toxic to mammals, though the feds say of relatively low toxicity. It is an acetylcholinesterase inhibitor, but is broken down quickly in mammals. It is *extremely* toxic to bees, and I think, fish IIRC. It remains one of the most widely used insecticides in American farming, but has been used much less in recent years by home gardeners. I suggest you do a search for "tiny holes in leaves of vegetable plants" and assimilate whatever advice you see in your search. There may be several effective ways of eliminating the problem with natural compounds. A safer, much less toxic chemical alternative (note I did not say it's "non-toxic") is gamma cyhalothrin, sold under the names "Spectracide", "Triazicide" and others. Frankly, it's not super effective, but it helps, and is safer in the long run than carbaryl. But at least check out natural controls first. I can't say specifically which ones, because the tiny holes in your leaves could be from a variety of different causes. Tony M. |

Thank you for the advice Tony. I'll do that search and try to find an alternative method of eliminating the insects. I saw a few of them on my plants. They are as small as a flea or gnat and when you touch one with your finger, they fly away. I sure don't want to use any chemical that will harm the bees. Our local bee population is in big trouble as it is. By the way Tony, did you ever hear about mixing a little dish detergent with water and using it as a bug spray? I just wonder if it would work or not? Sure would be less toxic than some of the other chemicals I would think. Rich |

I guess my question is: would this be a good general purpose insecticide for use in my vegetable garden? I just posted about Spinosad. It's a bacterium that works by killing the insects in the pupal stage when they feed on the plants. It is supposed be be very effective. I'll know soon if it fixes my leaf miner problem. It is toxic to bees but only when wet. Once dry it is supposed to be mostly harlmess to them. I sprayed at dusk after any bees had left so by morning the stuff was dry. It spares beneficial insects that do not feed on the plants such as spiders and praying mantii. |

I guess my question is: would this be a good general purpose insecticide for use in my vegetable garden? Rich from PA http://www.helpfulgardener.com/phpBB...pic.php?t=1595 "We do know that carbaryl is quite toxic to honey bees, certain beneficial insects such as lady beetles, and parasitic wasps and bees, certain species of aquatic insects, and some forms of shellfish such as shrimp and crabs. Care must be taken when using carbaryl in areas where these organisms exist." http://www.safe2use.com/poisons-pest...sevin-carbaryl -old.htm SEVIN (Carbaryl): A CONTROVERSIAL INSECTICIDE by Winand K. Hock Extension Pesticide Specialist Penn State University If you can believe the headlines which appeared in newspapers from the Delaware Valley and New Jersey last spring, the manufacturers of carbaryl (Sevin) must have developed and released to the public a 'chemical black death' which will make Love Canal, DDT, PCB's, and Kepone in the Chesapeake Bay seem rather insignificant. One Canadian environmental organization in a letter addressed to local citizens cites some of the 'documented' effects of carbaryl. 1. It causes birth defects in mammals, especially dogs. 2. It worsens the condition of people with hypertension and people on anti-depressant drugs. 3. It impairs the function of the pituitary gland, the thyroid gland, and the reproductive system. 4. It causes hyperactivity and learning disabilities in mammals. 5. It could increase the chance of heart attack in people with weak hearts. 6. The main break-down product, nitrosocarbaryl, which is easily created in the human gut, is a potent cancer-causing agent. 7. It causes irreversible chromosomal damage to human DNA (the genes in our cells). ---- You might expect some "blow-back", if you have any neighbors with vegetable gardens. -- - Billy "Fascism should more properly be called corporatism because it is the merger of state and corporate power." - Benito Mussolini. http://www.youtube.com/watch?v=Arn3lF5XSUg http://www.thirdworldtraveler.com/Zinn/HZinn_page.html |

After 3 or 4 days you can pull the cover and the lady bugs will spread out looking for more pests. Put a ladybug house out in the early fall and they will overwinter in it. Doug |
