How To Prepare A Greenhouse Fungicide Drench?

Soil drenching is a simple and economical method for maintaining plant and soil health. It requires minimal equipment, such as a bucket or watering can, a stir stick, chemical-resistant gloves, and a measuring tape. The most effective use of biofungicides is as a preventive treatment in growing media or as a seed treatment. They should be mixed into the growing media prior to planting or regularly applied to the root zone of plants.

A soil drench of a plant growth regulator (PGR) is an application of a relatively large volume of solution at a low concentration to the growing media. Fungicides applied as drenches have been important tools in preventing Rhizoctonia and halting its spread. Banrot and Hurricane are broad-spectrum fungicides that contain two active active ingredients.

To use a soil drench, start by removing visibly diseased plants and sanitation, such as removing plant debris and disinfesting pots and production surfaces. Mix four tablespoons of apple cider vinegar in a gallon of water for an effective fungal spray. Blend compost with water in a 5-gallon bucket and let it sit overnight. Strain and add to a sprayer or mix with more water to make a soil drench.

Using low-volume equipment can provide excellent coverage to plugs and cuttings with insecticides and fungicide without forceful application to the plants. The active ingredient in bleach is only effective as a surface disinfectant and not effective in treating the entire area. Spray uniformly over the area to be treated with a properly calibrated power sprayer or apply as a full coverage spray to run-off when conditions are favorable.
