Natural Insect and Disease Control: Kitchen Cures.

Salt sprinkled on slugs will reduce them to a glob of slime. Don’t use more than a couple shakes as salt in garden soil will kill many plants.

VLUU L100, M100  / Samsung L100, M100Coffee: A cup of strong coffee spray on plants can prevent the red spider mite. Coffee ground are high in nitrogen and will also benefit most soils greatly.

Horseradish mixed in water and used as a spray will repel potato bugs.

Cedar chips or sawdust: A tea made by soaking the chips or sawdust in hot water will keep away Mexican bean beetles, potato beetles, spider mites, mealybugs, cucumber and squash beetles. You can also just work the cedar into the dirt around plants for the same effect. Sprinkled on lawns the sawdust works well against chiggers.

Wood Ashes: Sprinkled around the base of plants will stop beetles, mites and aphids. Some people in certain areas claim wood ashes also work to repel deer, mice, cutworms, slugs and rabbits, being almost 80% effective.

Flour: dusted on cabbage plants after a rain or watering will cause worms to get all gummed up in the paste and dry out in the sun.

Natural Insect and Disease Control: Spider Mites.

spidermite-webSpider mites are so tiny, you will likely not notice them until you see their webs all over your plants and the plant looking diminished like the sap has been sucked out of the leaves.

Some agricultural sprays and products will actually encourage spider mites in orchards and on plants. Sprays with copper and zinc will increase the numbers of citrus red mites. Nitrogen-rich fertilizers increases the number of red mites and two-spotted spider mites. The citrus rust mite likes copper.

Spider mites are very sensitive to any changes in their habitat and predators and some chemicals have been found to upset the natural balance that keeps mites in check. They favor hot, dry weather, so keeping plants well watered and using an overhead watering system will help keep them in check.

Homemade spray for control: Dr. G. Edward Marshall of Purdue University found mixing wheat flour with buttermilk coats the mites and suffocates them with their hind ends up in the air. They get stuck in the glue-like mixture and some of the mites appeared to have exploded when the mixture dried. He made his mix thick enough to stick to surfaces but thin enough to spray through a high-pressured sprayer. You will probably have to experiment with your spraying equipment and the consistency of the mixture to get it to work with your equipment.

The ladybug is also a natural predator of mites.
