If late blight is present in your garden, remove the plant, roots and all, before the next rain to minimize the chances it will spread to other gardens and farms. Immediately bag the plant tightly in plastic and set in the sun for a few days until the plant dies off completely. Then dispose of in the trash. Do not compost. Do not leave it lying on the ground for later.
If you're not sure -- and chances are you won't be unless you get a professional diagnosis -- place suspect leaves in a sealed zipper-top plastic bag overnight. Late blight spores will develop into a fuzzy mass on the underside of the affected foliage.
Here are 10 things McGrath recommends you do to minimize late blight in your garden.
1. Kill volunteer potatoes. Dig up, bag and trash any potato plants that sprout from tubers left in the ground or compost pile last year. It may take repeated efforts to get them all.
2. Buy healthy tomato plants. Learn what late blight looks like. (See photo above) If you spot any infected plants while shopping, alert store management and your local Cooperative Extension office, and buy your plants somewhere else. Or you can grow your own plants. (Late blight isnt spread on tomato seeds.) Start seed about 6 to 8 weeks before your last frost date. 3. Use certified seed potatoes. Dont use leftovers from last years garden or table stock from the grocery store. 4. Keep plants dry. The late blight pathogen thrives in cool, wet weather. Thats because it requires moisture to infect plants, grows best when its cool, and clouds protect spores from lethal UV radiation when they are dispersed by wind. Even in absence of rain, the pathogen can infect plants if the relative humidity is 90 percent or more. If plants need watering, water the soil not the foliage.
5. Be vigilant. Inspect plants at least once a week more often if weather is cool and wet. Immediately remove and bag foliage you suspect might be infected. While late blight symptoms are distinctive dark brown lesions on stems and leaves with white fungal-like growth developing under moist conditions its possible to confuse it with other diseases. Your local Cooperative Extension office can help you with identification. 6. Act quickly. If symptoms continue despite removing infected foliage, consider removing plants entirely sooner rather than later. "It is rarely possible to control late blight just by removing affected tissue," McGrath said. "The longer you wait to remove plants, the more spores your garden sends to the wind to infect other gardens and farm fields." 7. Sound the alert. If you find late blight in your garden, let your gardening neighbors and local Cooperative Extension staff know so they can warn others and be on the lookout for additional infestations. Make sure your neighbors know how to spot late blight in their own gardens. 8. Dispose of plants properly. To reduce disease spread, remove infected plants during the middle of a sunny day after leaves have dried, if possible. But dont wait for these conditions. Seal plants in garbage bags and leave them in the sun for a few days to kill plants and the pathogen quickly before placing in the trash or burying underground or deep in a compost pile. Dont just leave plants on the ground or on top of the compost pile where they will continue to be a source of spores until the plant tissue dies. With a large number of plants, you can build a pile on the ground and cover securely with a tarp until the plants die. 9. Keep an eye on other tomato-family plants . Some strains of late blight can infect other tomato-family plants, including weeds such as hairy nightshade and bittersweet nightshade. Control them early so that late blight on these plants doesnt go unnoticed. Petunias and tomatillos are also vulnerable to attack. 10. Use fungicides with care. Fungicides can control late blight. ( Chlorothalonil and copper-based products are both available to home gardeners.) But if you wait until late blight symptoms appear, it might be too late to rescue plants. For fungicides to work effectively on late blight requires a regular preventive spray schedule and thorough spray coverage. Follow all label directions, including use of respirator, waterproof gloves and protective eyewear.
