Use of succinate dehydrogenase (SDH) inhibitors in the treatment of plant species from the family of the true grasses
View Patent ↗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.
