I grow hydroponics in a closed grow room environment in Deary Idaho. Peppers, tomatoes, strawberries and some eggplant (when they want to grow.
This summer I found a beautiful yellow banana pepper at a garden sale. I was careless in the isolation station and after two weeks brought it into my grow room.
BAD me! I soon found aphids on my peppers and I’m going nuts trying to wash and spray each plant and bud. They grow faster than I can wash!
I have tons (well maybe a few bottles) of chemicals but I don’t want to use them unless as a last resort.
Do you have a systemic preventive treatment for food vegetables?
Systemic are products which work their way inside plants and are distributed via sap and other plant components. Due to there invasive nature, it’s not an exact science and where the active will end up is sometimes not in the best interest of anyone that might be consuming parts of the plant. In other words you can sometimes get too much product in certain areas of the plant and if this was to happen at the harvest end (fruit or vegetable being picked), there would be inherent risks for anyone consuming the crop. For this reason systemic options are not suggested for any kind of food crop and though some exist, they are both expensive and limited in distribution. For the average grower which is growing something they wish to consume, alternative options are more practical and cost effective.
As explained in our APHID CONTROL ARTICLE, once this pest finds their way onto you plants, it can be a true uphill battle to completely eradicate the infestation. The key is persistence. And though it will take a long time to deploy and break the cycle, the use of INSECTICIDAL SOAP daily to all the plants can do the job. This product has no residual and will only work when applied. If used daily, you can effectively break the cycle by killing those which have hatched. Doing this for two weeks straight will usually clean off all the plants of any living and developing aphids and this can be done by either spraying or wiping them down with a mixed solution. Insecticidal Soap is organic and breaks down within hours of being applied so fruits and vegetables being harvested won’t pose a hazard to anyone that might consume them.
