Definitions

• the invention relates to the use of the fungicide Isoflucypram for controlling Claviceps purpurea and reducing sclerotia in cereals, to a method for treating cereal plants, plant parts thereof, for controlling Claviceps purpurea and reducing sclerotia in cereal plants.
• Claviceps purpurea is the fungus causing so called ergot in grasses like rye and ryegrass (principal economic hosts), barley, oats, triticale, wheat, and other cultivated and wild grass species in the subfamily Pooideae, including bentgrass, bluegrass and fescue.
• Claviceps purpurea is unique as the fungus only infects ovaries of the host plant. During the infection of the host plant the plant ovary is replaced by a blackish sclerotia often called an ergot or ergot body. The sclerotia are the overwintering spore form of the fungus which will partly be harvested with the crop and will partly fall to the ground.
• the sclerotia will need a vernalization period of about four to eight weeks with temperatures between 0 and 10 degree Celsius in order to break dormancy and germinate.
• the sclerotium consists of a whitish mycelial tissue containing storage cells and a dark pigmented outer cortex that protects the fungal mycelia from desiccation, UV light and other adverse environmental conditions. Due to its unique infection mode open pollinated cereal species are highly susceptible to infection, in particular rye and triticale.
• the main problem of the disease is besides yield reduction the toxic alkaloids of the sclerotia causing significant health issues both in animals and plants.
• Poisoning outbreaks are called ergotism and have already described in the middle ages where consumption of flour ground from rye seed contaminated with ergot bodies led to gangrene, mental hallucinations and convulsions.
• Claviceps purpurea infection benefits from cooler and more humid weather conditions during the flowering period of the cereal plant.
• the disease is managed using different techniques like seed cleaning, planting of clean seed, sanitation of field borders and weed control, crop rotation or deep plowing.
• the amount of sclerotia/ergot bodies is assessed in the grain, as it is highly difficult to assess the disease in earlier stages of the infection.
• the assessment of the amount of honey dew produced by the fungus during infection is not predictive for the amount of sclerotia present in the grain. Consequently the presence of sclerotia also called ergot or ergot bodies in harvested grain of different types is a grading factor e.g. in the Official Grain Guiding Guide of Canada.
• ergot or ergot bodies in harvested grain of different types is a grading factor e.g. in the Official Grain Guiding Guide of Canada.
• Already low levels of ergot will lead to downgrading of grain, in particular in grain of higher quality like registered, certified or breeder grade.

• Plants and plant cultivars which are preferably treated according to the invention include all plants which have genetic material which imparts particularly advantageous, useful traits to these plants (whether obtained by breeding and/or biotechnological means). These plants may have been modified by mutagenesis or genetic engineering to provide a new trait to a plant or to modify an already present trait. Mutagenesis includes techniques of random mutagenesis using X-rays or mutagenic chemicals, but also techniques of targeted mutagenesis, to create mutations at a specific locus of a plant genome. Targeted mutagenesis techniques frequently use oligonucleotides or proteins like CRISPR/Cas, zinc-finger nucleases, TALENs or mega nucleases to achieve the targeting effect.
• Genetic engineering usually uses recombinant DNA techniques to create modifications in a plant genome which under natural circumstances cannot readily be obtained by cross breeding, mutagenesis or natural recombination.

• Abiotic stress conditions may include, for example, drought, cold temperature exposure, heat exposure, osmotic stress, flooding, increased soil salinity, increased mineral exposure, ozone exposure, high light exposure, limited availability of nitrogen nutrients, limited availability of phosphorus nutrients or shade avoidance.
• Plants and plant cultivars which may also be treated according to the invention are those plants characterized by enhanced yield characteristics.
• Increased yield in said plants can be the result of, for example, improved plant physiology, growth and development, such as water use efficiency, water retention efficiency, improved nitrogen use, enhanced carbon assimilation, improved photosynthesis, increased germination efficiency and accelerated maturation.
• Yield can furthermore be affected by improved plant architecture (under stress and non-stress conditions), including but not limited to early flowering, flowering control for hybrid seed production, seedling vigour, plant size, intemode number and distance, root growth, seed size, fruit size, pod size, pod or ear number, seed number per pod or ear, seed mass, enhanced seed filling, reduced seed dispersal, reduced pod dehiscence and lodging resistance.

• Plants that may also be treated according to the invention are hybrid plants that already express the characteristic of heterosis or hybrid vigour which generally results in higher yield, vigour, health and resistance towards biotic and abiotic stress factors. Such plants are typically made by crossing an inbred male-sterile parent line (the female parent) with another inbred male-fertile parent line (the male parent). Hybrid seed is typically harvested from the male sterile plants and sold to growers. Male sterile plants can sometimes (e.g. in maize) be produced by detasseling, i.e. the mechanical removal of the male reproductive organs (or male flowers), but, more typically, male sterility is the result of genetic determinants in the plant genome.

• the foliar treatment of plants has been known for a long time and is the subject of constant improvements. Nevertheless, the treatment of plants gives rise to a series of problems which cannot always be solved in a satisfactory manner. For instance, it is desirable to develop methods for protecting the plant, the developing inflorescence and seed. It is additionally desirable to optimize the amount of Isoflucypram used in such a way as to provide the best possible protection for the plant, in particular the developing inflorescence from attack by Claviceps purpurea, but without damaging the cereals plant itself by the active ingredient used.
