The present application belongs to the field of kiwi fruit planting, and discloses a management method of kiwi fruit trees. The present application adopts a double-layer reverse U-shaped ring cutting method, which can slow down the downward transportation of photosynthetic products to a large extent and for a long time, effectively improves the yield and quality of kiwi fruit, reduces the risk of tree death, and balances the vegetative growth and reproductive growth of kiwi fruit. In addition, the present application provides a new type of composite control agent for brown spot disease and leafhoppers, which can more efficiently and scientifically control diseases and pests, thereby significantly improving the yield and quality of kiwi fruit.

The present application belongs to the technical field of lemon soot disease prevention and treatment, and particularly relates to a fungicidal composition for preventing and treating lemon soot disease. The fungicidal composition for preventing and treating lemon soot disease is composed of fluazinam and cnidim or composed of fluazinam and matrine; wherein, the synergistic mass ratio of fluazinam and cnidim is 1-8:20-1; the synergistic mass ratio of fluazinam and matrine is 1-7:9-1. The present application compounds fluazinam with other fungicidal active ingredients cnidim and matrine, which can improve the prevention and treatment effect on lemon soot disease compared with single component; at the same time, it can also reduce the resistance risk of single fungicidal component, which has important significance for developing fungicides for directly preventing and controlling lemon soot disease.

Methods of prevention, control and / or suppression of fungal pathogens in soybean plants, such as those pathogens that cause target spot, Septoria brown spot, frog eye leaf spot, white mold, and / or anthracnose, and compositions useful in such methods are provided. The methods generally involve applying a composition comprising zoxamide to a soybean seed, soil, a soybean plant or field of soybean plants that comprise, or are susceptible to, a causal agent of target spot, Septoria brown spot, frog eye leaf spot, white mold, and / or anthracnose.

This invention relates to the field of crop breeding, and in particular to a method for detecting and counting brown spot disease in rice. The technical solution includes: improving the YOLOv8 model by introducing the C2f-EFA module, the ASFPN module, the WSIoU loss function, and the TADHead detection head to optimize model performance, achieving efficient and accurate detection and counting of brown spot disease in rice, improving the accuracy and efficiency of brown spot disease detection and counting, and providing technical support for rice disease analysis. Specifically, the C2f-EFA module enhances the ability to express the features of brown spot lesions and diseased leaves, significantly reducing the number of parameters and computational complexity, making it suitable for resource-constrained brown spot detection scenarios; the ASFPN module effectively improves the model's ability to detect brown spot lesions and diseased leaves, making it suitable for scenarios with large scale differences, complex backgrounds, and small lesions; the TADHead detection head enhances the model's generalization ability for brown spot detection, strengthens the detection accuracy of brown spot lesions and diseased leaves, and ensures robustness under complex backgrounds or low contrast conditions; the WSIoU loss function significantly improves the accuracy of lesion and diseased leaf localization.
