What Is a Soil Drench?
As the name suggests, a soil drench is chemical in a liquid form that is used to drench or wet the soil under a sick plant or tree.

This insecticide is used as a soil drench or a spray and is helpful for control of many insects. It is absorbed by the plant and has a long duration of effect.

Apply Imidacloprid as a soil drench near the base of the trunk. Treatment should be made in the fall from late September to early November, for tree trunks larger than 4 inches in diameter at chest height. Smaller trees can be treated in the spring.

If that is not possible, try a soil drench - systemic granules that are sprinkled on the soil surface and watered in. If necessary, spray the plant with insecticidal soap or a recommended topical spray covering the top and undersides of the leaves.

In greenhouses, fungus gnat larvae can be controlled with a bacterial soil drench of a certain type of Bt (Bacillus thuringiensis), of which some trade names include Gnatrol and Knock-Out Gnats.

Fungicides may be applied as a soil drench after planting, incorporated into the soil as a dust before planting, or sprayed in mist form on all seedlings.

If there is an infestation spray it several times with a low toxic systemic insecticide and follow this up with a soil drench of the same product, as well as improving its growing conditions.

"Several systemic insecticides [such as Bayer 2-in-1 Systemic Granules or Ortho Systemic Insect Killer] are applied as soil drenches, so that the roots take up the toxicant and spread it to where the insects are feeding.
