Answer 1

This could be Powdery mildew caused by a fungus & looks like a white powdery growth on leaves and stems. Infected parts are stunted & distorted and leaves may drop from the plant (after turning yellow, then brown). Powdery Mildew may interfere with proper ripening & yield.The disease is prevelant in humid weather with frequent dew and temperatures between 70 and 90 degree. Here's a picture & info:

Mix 1 part milk to 9 parts water & spray.
Scientific & anecdotal evidence:
http://www.gardenguides.com/pests/tips/powderymildew2.asp
Wagner Bettiol, a scientist from Brazil, found that weekly sprays of milk controlled powdery mildew in zucchini just as effectively as synthetic fungicides such as fenarimol or benomyl. Not only was milk found to be effective at controlling the disease, it also acted as a foliar fertilizer, boosting the plant's immune system.
In his experiments with zucchini plants, Bettiol found that a weekly spray of milk at a concentration of at least 10% (1 part milk to 9 parts water) significantly reduced the severity of powdery mildew infection on the plants by 90%. Don't go overboard, however. Once concentrations rose above 30%, an innoccuous fungus began to grow on the plants.

It seems that milk is a natural germicide. In addition, it contains several naturally occurring salts and amino acids that are taken up by the plant. From previous experiments using sodium bicarbonate, potassium phosphate, and other salts, researchers have found that the disease is sensitive to these salts. It is possible then, that milk boosts the plant's immune system to prevent the disease.(1)

Melon growers in New Zealand are saving thousands of dollars every year by spraying their crops with milk instead of synthetic fungicides. The melon growers in New Zealand have been so successful that the wine industry is taking notice and beginning experiments using milk to control powdery mildew in grapes.

For the past 2 years, Peter Crisp of the University of Adelaide, Australia, has been spraying ordinary milk—diluted with water to a 10-percent solution—on grape vines at two commercial vineyards. He finds that in most cases, milk performs as well as the leading nonorganic powdery-mildew fighters—sulfur and a synthetic chemical known as Topas. He also has achieved about the same success with diluted sprays of liquid whey, a waste byproduct of cheese production.

Though more expensive than sulfur, milk and whey sprays cost less than synthetic fungicides. They're part of a battery of new agents that may permit organic vintners to continue exporting their wines into European and U.S. markets. (2)

Paul James, master gardener and host of Gardening by the Yard says he has successfully used Milk to get rid of mildew, just as his grandfather had done 40 yrs ago. He mixed 1 cup of milk with 9 cups of water. (3)

Take an infected leaf to your Agricultural Extension office for positive identification. Since you didn't say if it was a powdery white substance or a mold, I assumed it was Powdery mildew ... which doesn't kill the plants. If you said your plants were dying & had a white mold, then it would be Fusarium wilt.

Get rid of infected leaves & improve air circulation around the plants. I elevate my plants so they dry faster by putting stones & small rocks under them. Water early enough so there's not too much moisture around plants at night & don't water overhead on the leaves.

The female flowers come when it gets cooler.
Good luck! Hope this was helpful.

You have downy mold. You need to get a fungiside to get rid of it. Go to the hardware store and ask them for a fungiside for downy mold. Follow the directions on the package. Its best to find a powder.

sorry but there is absolutely nothing you can do, and well if they don't like you well they don't like you lol, do you talk to things you no don't understand you? you seem like that type of person,
