The Use of a New Ionic Derivative of Salicylic Acid in Sugar Beet Cultivation

Abstract

The need for sustainable development in the context of pesticide use has been recognized by the European Union. The “Farm to Fork Strategy” indicates a goal of 50% reduction in pesticide use by 2030. To address this challenge, we used the concept of ionic liquids to modify known resistance inducers, i.e., a group of substances whose action is indicated as an alternative to fungicides. A new, patented substance developed by us, which is a choline 3,5-dichlorosalicylate, has been tested in the context of its use in sugar beet cultivation with the aim of controlling Cercospora leaf spot (CLS). The results suggest that the use of this substance in combination with one fungicide treatment reduces disease infection and produces yields very similar to the use of a standard protection program assuming the use of two fungicides. Such results provide the basis for further development of 3,5-dichlorosalicylate in terms of its use in agriculture. Thanks to its use, it was possible to resign from one fungicide treatment, while maintaining protection against CLS and yields at the same level as for the full fungicide protection program. Such an approach is in line with European Union policies.

The Biostimulation Activity of Two Novel Benzothiadiazole Derivatives in the Tomato Cultivation

“…What is more, the need for sustainable development in the context of pesticide use is also demonstrated in "Farm to Fork Strategy", which indicates a goal of 50% reduction in pesticide use by 2030. In our previous work, we demonstrated such a possibility with the use of another ionic derivative named choline 3,5-dichlorosalicylate (3,5 diClSal) in the cultivation of sugar beet [39]. A similar level of protection against C. beticola and the amount of technological sugar yield was obtained as a result of treatment with a combined variant consisting of SAR inducer and fungicide (in a reduced number of treatments) as well as a variant consisted of standard fungicide treatment (SFP).…”
