Make your own organic insecticides and fungicides Researched by David P
Method 1 To make an all-natural pesticide, boil 1 cup of rhubarb leaves in 6 1/2 cups of water for 20 minutes, and strain the water. Add 1/4 cup of either liquid dish detergent or soap flakes. This pesticide works especially well against some beetles, aphids and spider mites. As rhubarb leaves are poisonous, don't use this pesticide on any food-bearing plants. Rhubarb leaves are poisonous to humans. They are high in oxalic acid as well as other toxins. Be wary of any rhubarb stalks affected by cold as they can also contain these poisons leached down from the leaves. The leaves can be added to compost in reasonable quantities as the composting process breaks down many of the toxins, and oxalic acid in particular is not absorbed by new plants, so it can be used in vegetable gardens.
Method 2 Make another type of all-natural pesticide by blending 2 hot peppers, 1 large onion, 1 bulb of garlic and 1/4 cup of water until it forms a mash. Pour 1 gallon of near-boiling water over the mash, let it stand for 24 hours, and then strain. To use the pesticide, spray it directly onto roses, azaleas or vegetables, or bury the mash in the ground. This pesticide is good for aphids, grasshoppers, and any type of chewing or sucking insect.
Method 3 To make a simple pesticide out of tomato leaves, crush the leaves from a single tomato plant, and soak them in water for two days. Strain the water, and pour it into a spray bottle to deter grasshoppers and white flies.
Method 4 1.5 cups of warm water 2 bulbs of cheap garlic squirt of diswashing liquid Bash garlic and add to water, add dishwash liquid. Leave to steep in container isn sun for a few weeks. Strain for use. Be prepared: it will STINK.
Other treatments For aphids, and many small flies – treat with pyrethrum insecticide, or try sprinkling leaves with wood ash or talc then hosing them down the next day. You could also plant ‘decoys’ such as nasturtiums, nearby and plenty of flowers to attract ladybirds - 'aphids’ natural predators.
