What measures may be taken to avert or control the late blight? – Cultural measures have a relatively little influence on the prevention of late blight since the disease prefers to infect plants during periods of rainy and chilly weather. Drip irrigation at the plant’s base is going to be of great assistance.

To improve the circulation of air, the plants in a row should have a fair amount of space between them, and the plants themselves should not be handled when their foliage is moist.
Mulching with plastic or an organic material will minimize the growth of early blight more than late blight, although these diseases frequently act together to damage tomato plants.

Early blight may be prevented by mulching with plastic or an organic substance. Tomatoes that are supported by stakes or caged will have their leaves dry out more quickly. Before you plant the transplants, make sure to check them for any signs of illness.

Try to avoid planting tomatoes in areas that were once used to grow potatoes or that are located nearby potato farms. It is possible to lessen the likelihood of late blight wiping out an entire crop of tomatoes by planting them in stages or sowing multiple crops over the course of time. Fungicide spraying is the most efficient method for preventing late blight from occurring.

Protectant fungicides like chlorothalonil (e.g., Bravo, Echo, Equus, or Daconil) and Mancozeb (Manzate) can be utilized by conventional gardeners as well as commercial growers. Organic gardeners have the option of using fixed copper products like as Kocide to protect their plants from late blight infestation.

Before applying any fungicide, make sure you read the label first. Consult the 2009 Commercial Vegetable Production Guide for information about fungicides that particularly target the fungus. If the conditions are right for the development of late blight, you should begin a weekly spray application as soon as the plants have been transplanted.

If this is not possible, begin applying protectant fungicides when the flowers begin to form in order to prevent late blight and other tomato diseases.

After you have poured the liquid into a spray bottle, give it a good shake and then apply it to the entire plant. Fungicides made from baking soda should be applied to plants out of the direct sunshine to prevent the plant from being scorched, and the solution should not be made too powerful.
