The invention provides a control method for apple alternaria leaf spot, and belongs to the technical field of crop disease control. The prevention and treatment method comprises the following steps: spraying a foliar biological pesticide fertilizer to apple trees; the foliar biological medical fertilizer comprises a bacillus fermentation product and a trichoderma fermentation product, the bacillus is at least one of bacillus amyloliquefaciens TS-1203, bacillus subtilis B1 and bacillus subtilis BS-1208, and the bacillus is at least one of bacillus amyloliquefaciens TS-1203, bacillus subtilis B1 and bacillus subtilis BS-1208; the trichoderma is at least one of T6 and Ym. The combined action of bacillus and trichoderma is utilized, the morbidity of apple alternaria leaf spot can be effectively reduced, the growth of apple trees can be promoted, the photosynthetic capacity is improved, the combination of disease prevention and yield increase is realized, and the method is environment-friendly and suitable for green agricultural development.

The application belongs to the technical field of apple molecular breeding, and particularly relates to application of a detection reagent of a molecular marker related to apple anthracnose leaf blight resistance, the molecular marker being Del772, Del231 and SNP947, the nucleotide sequence of Del772 being shown as SEQ ID NO. 1, the nucleotide sequence of Del231 being shown as SEQ ID NO. 4, and the nucleotide sequence of SNP947 being shown as SEQ ID NO. 5, the application further develops the detection reagent of the molecular markers Del772, Del231 and SNP947, the detection reagent can detect or identify the resistance of apples to anthracnose leaf blight, and a method for identifying the resistance of apples to anthracnose leaf blight is developed, thereby providing a new way for breeding disease-resistant apples.

The present application belongs to the technical field of apple planting, and discloses a method for preventing and controlling apple bitter scab, which comprises the following contents: (1) nitrogen fertilizer regulation, adopting a strategy of applying fertilizer in stages, including application of base fertilizer in autumn, application of topdressing fertilizer in spring, and nitrogen limitation management in summer; (2) new shoot regulation, setting differentiated new shoot growth thresholds according to the age stages of fruit trees; (3) fruit regulation, controlling the fruit retention position and amount through thinning flower and fruit management, and controlling the fruit size within a preset horizontal diameter range; (4) whole-cycle calcium supplementation, establishing a three-dimensional calcium supplementation system including foliar spraying in the growing season, root zone application, and post-harvest treatment. The present application effectively guarantees the quality and yield of apples, reduces the influence of bitter scab on the growth and development of fruit trees, thereby realizing high-quality, high-yield and high-efficiency of apples, and promoting the high-quality development of the apple industry.

The present invention relates to the use of a fungicide selected from the group of phosphonates, in particular Fosetyl-Aluminium, either alone or in combination with a fungicide selected from the group of succinate dehydrogenase inhibitors, in particular Fluopyram for reducing the fitness costs associated with infections of scab resistant and scab susceptible apple plant varieties with Venturia inaequalis. The invention further relates to the use of said fungicides to delay the leaf senescence process in apple.

The application discloses a structural variation marker in apple scab resistance breeding and application thereof. The application claims the application of a specific fragment as a molecular marker in detection or assisted detection of apple plant resistance to scab; the nucleotide sequence of the specific fragment is as shown in SEQ ID No. 1 or positions 393-1166 of SEQ ID No. 1. Experiments prove that the absence and presence of the SCAB-R fragment (SEQ ID No. 1) can be used to quickly screen the scab resistance potential of natural plants or hybrid offspring, which is of great significance to the scab resistance breeding of apple plants.
