Seven dust - Applied a month ago - Still toxic or not ?
Last month ( mid June ) I had applied Seven dust to my grapevine
due to Japanese Beatle infestation. I applied by hand ( gloved ). I grabbed a handfull at a time and just tossed it across the whole of the foliage and grape clusters. Here it is mid July and I still see some rather rich deposits of the dust sitting on the clusters. As these grapes ( type unknown ) are reaching ripeness they will no doubt be harvested within the next 2 weeks to make wine. Will the residual Seven dust pose any health threats at this point ? I've tried rinsing with a garden hose but to no avail. It is rather "caked" in some areas. There might have been some moisture on the grapes when I slung the seven dust causing it to do so. TIA Paul |

A month has passed. Two more weeks until they're ripe enough to pick. I guess it wouldn't hurt to try to wash/rinse the individual grape bunches with mild soapy water and use a paint brush to scrub with. I've had a bumper crop this year and would hate to loose all those pretty grapes. Then again getting poisoned over it doesn't sound very inviting. Do you suppose my idea of washing the bunches off to be a realistic solution ? = Paul = |

Just first aid ( after the fact ) and prevetitive info. Or did I miss something ? Thanks for the pointer. = Paul = |

If that appears to rid the grapes of the residue then I will continue towards making the wine with your suggestions in mind. = Paul = |

As far as the half life of Sevin (not seven): http://extoxnet.orst.edu/pips/carbaryl.htm Note that carbaryl is bound by organic matter. Personally, I wouldn't touch these grapes. |

I would call the manufacturer and ask them. You might also consider getting a back pack sprayer. In the future, consider Imidan. It is suppose to be more friendly to beneficals and it will kill the beatles. Also, the beatles do not eat the fruit so there really is no need to use the seven on them. I only use pesticides on the fruit if I see a heavy infestation of the Grape Berry Moths. The beatles eat the youngest shoots at the top of the canopy, not the older leaves or the fruit. |

The dust was given to me in a mason jar by my girlfriends father, complete with no instructions. Just toss it across the whole of the vine like he does his peach trees. So that is what I did. If you don't have anything more constructive to offer than your sarcastic critisism, please keep it to yourself. = Paul = |

Yes. But I was hoping that a 6 week duration might be long enough for the dust to break down in toxicity. My neighbor puts the stuff on all her greens ( collard, cabbage, turnip etc ). She pounces it on with an old nylon stocking. In fact, she does the same with her corn (at the silk end of the ear just as soon as soon as silk appears). I know one thing. I'll never use Sevin on my grapes again. I used to use a Pyrethrin based pesticide ( Tiger Brand ) but haven't seen it at the store this year. It breaks down rather quickly and most veggies can be ingested within a week after it's use. The Sevin was given to me and I tried it. I made a mistake. All I want to know now is ( and I thought that was clear ) has enough time passed to degrade the dust enough or would it still be hazardous ( ... and would washing them be of any use ) . In two weeks I will pick said grapes. I will attempt to wash the bunches by hand. Depending of that outcome, I will either prepare them for wine or if washing doesn't seem to remove the residue I will trash those bunches that won't wash clean. = Paul = |

Depending of that outcome, I will either prepare them for wine or if washing doesn't seem to remove the residue I will trash those bunches that won't wash clean. As someone else pointed out, the grapes will have absorbed the Sevin. No way would I ever eat them or use them in wine. Sounds like that was a really expensive gift you got. Japanese beetles are easily knocked into a bowl of water to drown and sure when they're at peak you have to do it every day but it still beats poison. |
