A DRIP-FREE MECHANICAL SYSTEM FOR APPLICATION OF CHEMICALS ON PLANTS |
| Author: | R.S. Bijl |
| Abstract:
Normally the chemicals used in agriculture and horticulture are applied to plants by spraying or fogging. In this way part of the chemicals will end up in places where they are ineffective or even undesirable, for instance in paths, on the fields nearby, on construction parts of a glasshouse or on the glass façade. An example of this problem is the use of silver thiosulphate (STS) in flower culture of lilies in winter. Application of STS prevents bud blast, caused by shortage of light in this season. Leakage of this chemical into the glasshouse soil is considered highly undesirable from the point of view of environmental protection. Therefore, a mechanical wetting method was developed, based on a wiping action. A drip-free rotating applicator is moved along the plants, wetting them along the whole stem. Although primarily developed for STS application in lilies (a method that for various reasons has not been introduced into practice), this method is also suited for waste-free application of systemic agents. | |
