How to Control Downy Mildew in the Garden
How to tell this from mosaic virus? In our raised beds, we have some beans that are showing signs of leaf mottling, curling and dying leaves and stunted growth, especially the runner beans. Peppers have curled leaves on the new growth and stunted growth. My carrots are fine. Potatoes and tomatoes are yellowing as well. We can't afford to start to over, it has taken us years to get those beds full of good organic soil. I've invested so much money in heirloom seed. There is so much conflicting information online and so many different types of mosaic. We are not sure whether to plant anything in the in-ground garden because I've read mosaic can be hosted by weeds and with all the rain we've had this spring the weeds are getting out of hand on the perimeter, outside of the ground cover. Obviously we can get rid of the weeds, I can dispose of the infected plants, but is it in the soil? It definitely looks like mosaic, comparing my bean leaves to pictures online. But, we are not 100% sure and don't know what to do.
Oh yes! Am well familiar with this condition! I have a greenhouse and mildew just loves my zucchini and cuke plants but also loves green beans! My basil is just fine. I cut off the leaves affected and discard. Outside of that no clue how to prevent because I have drip lines,, mulch, lots of sun and temp controls. Oh well….will just keep plodding along!
