INSECT AND DISEASE CONTROLS FOR THE GARDEN
As an organic gardener, I like to remind myself that I’m looking for insect control, not insect eradication. If the plant health is not in jeopardy, or there is no huge crop loss, I will choose these remedies before any other.
• Insecticides will kill off beneficial insects too.
Cabbage worms - Use self-rising flour from your pantry.
Put flour into a paper bag and poke holes in the bottom. Sprinkle over plants in early morning when worms are actively eating. As the temperature rises, the ‘self-rising’ flour will swell the worm!!
Slugs - A shallow lid with beer placed under vulnerable plants will lure slug in – and they won’t come out!
A half and half mixture of ammonia and water sprayed on slugs will kill the slugs and the ammonia will convert into nitrogen which your plants can use!
Mix One cup coffee (strong) to 10 parts water and spray around base of plants and over the leaves. The caffeine is a killer!
Squash bugs are difficult to control. Clear any debris from planting area before planting. Use a mulch of newspapers and hay and cover bed tightly with row cloths. Remove before female blossoms appear for pollination to occur.
Diatomaceous earth and neem oil have some effect on this pest.
Some companion plants for squash are catnip, tansy, radishes, marigolds, nasturtiums, and mint.
This is the way nature takes care of its own.
The Hover fly lays its eggs on plants. When the larvae hatch, the larvae feast on hundreds of aphids a day.
Remember, insecticides kill all bugs.
3 T baking soda
2 T Murphy Soap
2 T Canola oil
2 T White Vinegar
2 Gal. warm water
Mix all ingredients and apply with a spray dispenser until foliage is completely wet. Do not spray on bright sunny days, as sunlight can burn leaves
.(An organic fertilizer of calcium nitrate may be added to limit blossom end rot in small gardens)
Consider a strict watering regiment in the vegetable garden to eliminate some over and under watering problems such as blossom end rot.
Effective Watering Practices
Onions broccoli, cauliflower, carrots and peas
Water once a week: peppers, beans, corn, squash, cucumbers and eggplant
Water once every two weeks: Tomatoes and melons
To prevent cracking, when plants are really producing a lot of fruit, increase watering of tomatoes to once a week.

These pest seem to be able to invade and destroy our gardens. Just remember that random spraying with pesticides may actually increase the problem. Even these home-made remedies can't distinguish 'good' bugs from 'bad' bugs.
