![]() ![]() Based on zoxium and mancozeb, Electis has been proven in the laboratory and in the field to be a particularly rainfast fungicide," reports Andy Leader, Principal Biologist for Dow AgroSciences.Īccording to Andy, the rainfastness of Electis is largely due to the lipophilic nature of one of its actives, zoxium. Farmers need to be confident that when they apply a blight fungicide, it stays on and in the plant and is not washed off. In many circumstances when blight control falls down, it is often due to the lengthening of the spray interval, planned or otherwise. "Farmers need blight fungicides that make the most of the spray days available and give them the best opportunity to keep to their planned spray intervals. In order to ensure complete and effective protection of the canopy, blight products must be rainfast and weather proof, especially if the weather is showery and when the majority of the crop is irrigated, says Dow AgroSciences. Blight in potatoes is characterised by a rapidly spreading, watery rot of leaves which soon collapse, shrivel and turn brown.Successful potato blight control relies on using effective blight fungicides at appropriate times and spray intervals from crop emergence right through to harvest. What does blight look like on potatoes?īlight in potatoes is characterised by a rapidly spreading, watery rot of leaves which soon collapse, shrivel and turn brown.

Michigan State University Extension reports that many growers have turned to Elixir fungicide ( mancozeb + chlorothalonil, 62.5 +12.5 percent, respectively from United Phosphorus) as the base control for potato late blight. Which is the best fungicide for potatoes? Burn off two to three weeks before harvest to prevent tuber infestation. Continue spraying at 7 day intervals up to the time of burning off. Start spraying main crop potatoes once the foliage is 10-15 cm tall. When should potatoes be sprayed?įungicides are used to prevent blight entering a potato crop and spreading through the crop. These are the main source of infection for next year's crops, as are dumped tubers in piles or on compost heaps. Does potato blight stay in the soil?īlight will not survive in the soil on its own, but it will remain on diseased tubers left in the ground. ![]() Blight is a fungal infection, and we recommend that you destroy the whole crop if you get an infection!

What to do with potatoes that have blight? Beyond that it is essential for the economic efficiency of the treatment that the choice of the product is adjusted to the infection pressure. Spraying fungicides should begin 7 to 12 days before late blight appears in the plot. For maximum protection from potato blight, crops should be sprayed four times a year, with 10 day intervals.When should you start spraying potatoes for blight? It is rain-fast within 1 hour, so should be applied immediately. You simply spray your plants to protect them from the blight fungus spores. ![]()
