Surfaplus shares research with growers on IPM
What are the benefits of adjuvants? Surfaplus
informs visitors of IPM Essen firsthand about research results in
ornamentals and greenhouse vegetables. 27, 28, 29 and 30 January you are welcome in our stand (Hall 8.0 Stand 8B24) and we will answer your questions about adjuvants and their application.
In this SurfaPlus - Tips & Tricks issue a preview on recently finished experiments.

Research and development
SURfaPLUS is an innovative company in Wageningen (The Netherlands)
specialized
in adjuvants for a more effective plant protection and plant growth
regulation. SURfaPLUS develops adjuvants and applications of adjuvants
in collaboration with the producers of adjuvants.

Adjuvants reduce costs of growth regulation
Growers
of pot plants and bedding plants can save on the costs of growth regulators by adding the
adjuvant
Elasto G5 to the spray solution. Growth regulator costs can be reduced
by at least forty percent, according to studies by the independent
agricultural consultancy provider DLV
Plant with a range of ornamental plant species and cultivars. In these experiments, DLV Plant successfully reduced or
even halved the dose of the growth regulator and added
the adjuvant Elasto G5 to the spray solution.
| • |
Elasto G5 and Atplus enhance the foliar uptake of active ingredients and improved the wetting of difficult-to-wet crops. |
| • |
Atplus is used with daminozide in chrysanthemum and Pernettya. |
| • |
Elasto G5 is used in other ornamentals as Atplus is often too hard in these ornamentals. |
| • |
Elasto
G5 is used with daminozide in hydrangea, kalanchoe, petunia, sutera,
campanula, platycodon, sunflower, Viola cornuta, potted chrysanthemum,
Dahlia, Dahlietta, Solanum rantonettii, lavender and pelargonium. |
| • |
Elasto G5 can also be used with chlormequat in poinsettia in order to reduce the number of applications. |
| • |
Elasto G also improves the performance of mepanipyrim against powdery mildew. |

Conclusion: Even when one takes into account the costs of the adjuvant a substantial reduction of costs is possible.

Better control of spider mites and thrips
Cucumber
growers can significantly improve the control of spider mites by adding
the adjuvant Hasten to a spray solution of abamectin (Vertimec).
Addition of this biodegradable adjuvant increases the uptake of
abamectin in the leaves, which results in a significantly enhanced
effectiveness of the active ingredient.
Pepper
growers can also significantly improve the efficacy of abamectin
(Vertimec) by adding the adjuvant Hasten to the spray solution.
Researches at Proeftuin Zwaagdijk have found this in experiments with
pepper plants infested with Californian thrips.
Hasten is an esterified rapeseed oil with food-grade - and thus food
safe - emulsifiers. In experiments with cucumber and pepper, this
adjuvant did not lead to any damage to plants or fruits.
Despite
the increased uptake of active ingredient in these experiments, the
abamectin content in cucumber and pepper fruits remains well below the
maximum residue limit (MRL).
|
|
|
Tip
When you combine Hasten with systemic compounds in vegetable crops, please pay attention to the maximum residue limit (MRL).
