Use of succinate dehydrogenase (SDH) inhibitors in the treatment of plant species from the family of the true grasses
The use is described of at least one succinate dehydrogenase (SDH) inhibitor for increasing the biomass of the flag leaf, of leaf F-1 and/or of leaf F-2 of the plant of plant species from the family of the true grasses (Poaceae).
1. A method of increasing the biomass of a plant comprising applying a biomass-increasing effective amount of bixafen to a plant in need of said increasing,
wherein the bixafen is applied at not less than two times in the development of the plant:
(a) the first application takes place at a time during development stages BBCH 17 to 42 of the plant, and
(b) the second application takes place at a time during devlopment stages BBCH 43 to 70 of the plant, and
wherein the plant is a non-transgenic plant, and is a species from the family of the true grasses (Poaceae).
2. The method of claim 1 , wherein the biomass of the plant flag leaf, leaf F1, leaf F2, or a combination thereof is increased.
3. The method of claim 1 , wherein the biomass of the flag leaf of the plant is increased.
4. The method of claim 1 , the biomass of ears, cereal kernels, cereal kernels per ear, or a combination thereof is increased.
5. The method of claim 1 , wherein said method simultaneously improves the physiological condition of the plant.
6. The method of claim 5 , wherein green leaf area duration of the plant is prolonged.
7. The method of claim 5 , wherein photosynthesis rate of the plant increases.
8. The method of claim 5 , wherein an increased chlorophyll content, a stabilized chlorophyll content, or a combination thereof is obtained in the plant.
9. The method of claim 5 , wherein delayed senescence of the plant is obtained.
10. The method of claim 5 , wherein resistance and tolerance of the plant toward abiotic stress factors is increased.
11. The method of claim 1 , wherein the method further comprises applying at least one active ingredient selected from the group consisting of spiroxamine, fluoxastrobin and prothioconazole.
12. The method of claim 1 , wherein bixafen is applied with a dose of between 0.01 and 3 kg/ha.
13. The method of claim 1 , wherein the plant is selected from the group of true grasses consisting of wheat, rye, barley, oats, millet, maize, rice, triticale, bamboo and sugarcane.
