Abstract:
The invention relates to a method for increasing the resistance of cultivated plants to chemical stress, triggered by insufficiently selective herbicides, or incorrect use of herbicides. The method is characterised in that the cultivated plant is treated with prohexadione or the salts thereof, in particular, calcium salt (I), which are suitable for use in agriculture.
Abstract:
The present invention relates to the use of a combination of acylcyclohexanedione carboxylic acid or salts thereof and acylcyclohexanedione carboxylic acid esters for improving the development of gramineous plants. The invention also relates to a method for improving the development of gramineous plants in which the plants or plant sections thereof are treated with said combination.

Abstract:
The present invention relates to a method of protecting grapevine plants against grapevine yellow disease caused by the phytoplasms Bois noire and/or Flavescens doree, which comprises treating the shoots or the soil in root proximity with an effective amount of a compound (I) in which R1 is hydrogen or C1-C4-alkyl and R2 is C1-C4-alkyl or C3-C6-cycloalkyl, or agriculturally acceptable salts thereof. In addition, the invention relates to the use of combinations of a compound (I) for inducing tolerance of grapevine plants to Bois noire and/or Flavescens dorée.
Abstract:
The present invention relates to the use of an active compound that inhibits the mitochondrial breathing chain at the level of the b/c1 complex for improving the tolerance of plants to low temperatures.
Abstract:
A method of enhancing resistibility of crop plants against bacterial and/or fungal diseases, which comprises treating the plants or seeds with low rates of 2-{1-[4-(3,5-difluorophenyl)semicarbazono]ethyl}nicotinic acid, common name diflufenzopyr, a method for controlling harmful fungi and bacteria using mixtures of diflufenzopyr and compounds Il and/or III, and also compositions comprising these mixtures.
