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 a method for applying an aqueous, pesticide-containing dispersion of a polyurethane which is a reaction product of at least one polyol (A) and at least one polyisocyanate (B) onto plants or plant parts. The invention also relates to an aqueous, pesticide-containing dispersion of a polyurethane which is a reaction product of at least one polyol (A) and at least one polyisocyanate (B). The invention further relates to the use of the dispersion for controlling phytopathogenic fungi and/or undesired plant growth and/or undesired insect or mite infestation and/or for regulating the growth of plants by letting the dispersion act on the respective pests, their biotope and/or the plants and plant parts to be protected from the respective pests, the soil and/or on undesired plants and/or useful plants and/or their biotope.
Abstract:
The present invention relates to compositions which, in sprayable or form, are suitable as wound sealants for woody plants. The invention also relates to a method of protecting woody plants from infection with phytopathogenic fungi, in particular ESCA infection, using such wound sealants. These compositions comprise: a) a water-insoluble sealing agent in dissolved or dispersed form, which is selected among film-forming water-insoluble polymers, waxes and their mixtures; b) at least one plant protectant, c) at least one volatile diluent, in particular an aqueous diluent, and, if appropriate, d) at least one nonionic surface-active substance in an amount of from 10 to 100% by weight, in particular 10 to 80% by weight, based on the sealing agent.

Abstract:
Disclosed is a liquid composition comprising a) a water-insoluble sealing material in dissolved or dispersed form, which is selected from among water-insoluble film-forming polymers and waxes and their mixtures, in an amount of 1 to 40 percent by weight, based on the total weight of the composition; b) at least one plant protectant e.g. strobulins; c) at least one volatile diluent, wherein the diluent comprises at least 70 percent by weight of water, based on the total amount of diluent; and d) at least one nonionic surface-active substance in an amount of from 10 to 100 percent by weight, based on the sealing material.
Abstract:
Disclosed is the use of an active compound for combating ESCA, wherein the active compound is selected from pyraclostrobin, dimoxystrobin, 2-(ortho-((2,5-dimethylphenyl-oxymethylene)phenyl)-3-methoxy-acrylic acid methyl ester, picoxystrobin, trifloxystrobin, enestroburin, orysastrobin, metominostrobin, azoxystrobin and fluoxastrobin, which comprises treating the fungi, their habitat or the plants, soils with and effective amount of at least one active compound.
Abstract:
Fungicidal mixtures comprising (1) boscalid of the formula (I) and (2) pyrimethanil of the formula (II) in a synergistically effective amount, methods for controlling harmful fungi using mixtures of boscalid (I) and pyrimethanil (II) and the use of boscalid (I) and pyrimethanil (II) for preparing such mixtures, compositions comprising these mixtures and also seed comprising these mixtures.
