Recipe for small garden enthusiasts through to large scale horticulturalists

Tobacco (Nicotiana tabacum)
Tobacco contains nicotine, which can be used as a potent insecticide. (Be careful, as nicotine is a poison and high concentrations can be lethal.) Target organisms include aphids, cabbageworms, caterpillars, flea beetles, grain weevils, leaf miners, mites, stem borers, thrips, rust, some fungi, and leaf-curl virus. Note: Do not use on tomatoes, eggplants, peppers, or potatoes.
Recipe:First, dry and pound the leaves (home grown green leaves - our leaves are ready to use as they are delivered so no drying is required) . Add 20 grams of tobacco to 1 liter of water, soak overnight, and apply during the evening watering. You can add up to 20 litres of water to this concentrate and a small amount of dishwash liquid which acts as a wetting agent to get more out of your investment, it is weaker but still works perfectly, simply apply generously around the base of your plants in the soil and to the leaves and stems.
For large scale use you boil the leaf in a large pot for as long as an hour ensuring you add more water as the water reduces, the longer you boil the leaf the stronger your pesticide will be and the more you will get out of your investment. For large scale applications one pound of leaf will make up to 500 litres of gentle insecticide that you apply to plants prior to fruiting.
