ORGANIC PESTICIDES AND NATURAL INSECTICIDES FOR A HOMEMADE PYRETHRUM SPRAY

Pyrethrum is by far the most effective natural insecticide and miticide there is and kills most aphids, cabbage loopers, celery leaf tiers, codling moth, Colarado potato beetles, leafhoppers, Mexican bean beetles, spider mites, stink bugs, several species of thrips, tomato pinworms, and whiteflies, flies, gnats, mosquitoes and midgies.

As soon as insects come into contact with the spray, they will die, attacking the nervous system. Pyrethrum is an African flowering plant from the chrysanthemum family and is deadly to most insects. However, because it is not systemic and is destroyed by UV light, it is not deadly to mammals and can be safely sprayed on vegetables and fruit when picked 12-48 hours after application. Unfortunately, it is also deadly to good bugs as well, so use with care and only spray on heavily infested plants as a last resort.

Spray both the upper and lower surfaces of the leaves, because spray must directly contact the insects such as thrips that hide in leaf sheaths and crevices. Spray in cooler temperatures as it is more effective then, evening or late afternoon being ideal. Never use pyrethrin products around waterways and ponds. And for those of you who have dermatitis, asthma and sinus you may have an allergic reaction when using pyrethrum.

Grow your own pyrethrum from seed, which can be bought from your local seedman and use the flowers that are in full bloom. The active ingredient is found in the immature seed. Cut them off early in the morning and hang upside down to dry and leave in a well-ventilated dark place to dry. Light will cause the plant to lose its potency. When dried, grind with a pestle and mortar until you have a fine powder.

Mix 10 gm of pyrethrum powder to 3 litres of water. Let stand for 3 hours in a dark place. Add 1 teaspoon of dish washing liquid as a fixative just before use.

You can also steep your flowers in a jar filled with boiling water, and apply after it has cooled down.

However, the best way is to cover the flowers in a container with brandy, although kerosene and mineral oil will also work but not as well. Leave this mixture overnight keeping it away from any light. Strain the liquid and use 1 part liquid to 6 parts water.

To store your flowers place them in a freezer up to 6 months and use accordingly.

ORGANIC PESTICIDES AND NATURAL INSECTICIDES FOR A HOMEMADE RHUBARB SPRAY

This is a very effective general spray that is extremely poisonous, however unfortunately it is also poisonous to bees so use with care, and keep out of reach of children.

Boil 1.5 kg rhubarb leaves in 3.5 L of water, straining and bottling. Dissolve 100 g soft soap in 2 L of hot water and add to the leaf mixture when cold.

Use only on ornamental shrubs, and flowers, but NEVER on herbs or vegetables.

ORGANIC PESTICIDES AND NATURAL INSECTICIDES FOR A HOMEMADE SOAP SPRAY

This is useful against aphids and some caterpillars.

56 g of soap flakes or pure grated soap mixed with 5 L of hot water, which must be cooled before use.

ORGANIC PESTICIDES AND NATURAL INSECTICIDES FOR A HOMEMADE SUGAR SPRAY

This organic spray control is effective against nematodes. Dissolve 2 kg sugar in a bucket of water. Drench the soil to kill nematodes. Molasses can also be used, but don't use honey as this may transmit disease back to the bees.

ORGANIC PESTICIDES AND NATURAL INSECTICIDES FOR A HOMEMADE TOMATO LEAF SPRAY

2 cups of chopped tomato leaves

2 pints of water

1/4 tsp of liquid soap

Soak tomato leaves in water overnight. Strain this mixture then add another pint of water and liquid soap. Spray foliage and soil as needed. This spray is effective against asparagus beetles and flea beetles, ear-worms and maggots.

ORGANIC PESTICIDES AND NATURAL INSECTICIDES FOR A HOMEMADE WHITE OIL SPRAY

White Oil can be purchased at your local gardening store at great expense. Or, you can make your own at a fraction of the cost using the same simple ingredients!

This is effective against scale. Pour a cup of cooking oil and a few drops of washing-up detergent into a 1 L plastic bottle.

Add 1/2 cup of water and shake well. Pour 250 ml into a 9 L bucket of water and mix.

Spray the mixture over and under infested leaves.

ORGANIC PESTICIDES AND NATURAL INSECTICIDES FOR HOMEMADE WORMWOOD SPRAY

This is effective against fleas, flies, moths, mosquitoes, aphids and snails.

Collect large amount of wormwood leaves and cover with a bucket of boiling water. Steep for 3 hours. Dilute, using 1 part mixture to 4 parts water. Allow to cool before using.

ORGANIC PESTICIDES AND NATURAL INSECTICIDES FOR GETTING RID OF FLEAS

Add a little sulphur to the dog's drinking water. Another method is to put 1/2 cup vinegar into the final rinsing water of your dog's bath water. Another is to boil a large quantity of mint leaves in 2 L of water. Strain and cool. After washing and rinsing the dog, pour the cooled mint solution over the dog and allow him to dry off naturally. Any fleas that remain will leave immediately.

ORGANIC PESTICIDES AND NATURAL INSECTICIDES FOR GETTING RID OF CANE TOADS

For those of you who live in Australia, and particularly Queensland, you are probably plagued with cane toads. Using them as golf balls in the dark is not very humane, although a common practice for the desperate! However, if you fill up a sprayer with pure Dettol and spray the cane toads directly, they will die almost immediately.

Large numbers can be rounded up and placed in a bucket and then doused with Dettol. Not strictly organic but it does work, and I talk from personal experience! Wear gloves and protective eye-glasses so you are not affected by their poison yourself.

ORGANIC PESTICIDES AND NATURAL INSECTICIDES FOR GETTING RID OF FRUIT FLIES

The best way to do this is to set up fruit fly traps in the orchard. These can be made out of jam jars, or old ice cream containers and then strung up in the tree boughs.

Prepare 300g pulped oranges, 15 g ammonium carbonate (purchase from the chemist), and add 600 ml water. Mix and fill jars or buckets with the bait.

Natural pest control is always better than toxic insecticides and pesticides as they usually only target the pest at hand, and are not harmful to bees and other useful insects.
