My squash plants have white powdery mildew, which has begun to spread to my zucchini and cucumbers. I went to Lowe's to purchase a treatment for the mildew. I was advised by two garden center employees to use Disease Control, which is manufactured by Bayer Advanced. The active ingredient is Tebuconazole (2.9%). We sprayed the plants last night and checked on them this morning. The white powdery mildew did not seem to be affected by the fungicide. So, I called Bayer's 1-800 question line. The woman informed me that this product is not to be applied to plants used for food. She could not give me any further information. The Poison Control Hotline and the National Pesticide Information Center could not offer any additional information either. If you have any information concerning this fungicide, please share. I am heartbroken at the thought of having to destroy my garden that I have worked so hard on. Thanks, Elizabeth
For future reference: Baking soda mixed with water is an organic method of dealing with powdery mildew. Also, anything with sulphur will work. Molasses mixed with water and sprayed on the plants acts as an organic fungicide. LoreD
I always reach for sulphur compounds- I'd take a complaint straight to the people in charge at Lowe's. Here's a website that might be helpful to you http://www.pesticideinfo.org/Detail_Che ... Id=PC35028
powerdy mildew i went on line and looked this product up. in ny state it was denied a permit for being unsafe for home use. but, i found another site that says it can be used for mildew but to use extreme caution. it was first used as an injectable for the preservation of wood and wood treatment.if it was me i would rinse my plants as soon as possible and dilute it well. then i would remove any infected growth to increase air circulation. let the plants dry well before watering again. heat and moisture promote mildew growth. so water early morning not at night. make sure to clean your tools with bleach to avoid spreading it to any other plants. but the choice is yours. i would suggest you read on line a few articles your self and make your own decision.
I use equisedum tea (horsetail), It works great for most all problems, but very well for DM. if the disease persists, a flowable copper soap, both great and organic. and I second the baking soda. The product you purchased,It had no details stating it was not for consumables?
