Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of planting and cultivation of southern fruit transplanted to northern planting, in particular to a tool for removing anthracnose lesions of pitaya and a treatment method. BACKGROUND

[0002] Pitaya (scientific name: Hylocereus megalanthus) is a new tropical fruit, originally from the Andes region of South America, belonging to the cactus family of Hylocereus. Its fruit is yellow and scaly, with a semi-transparent white flesh, rich in dietary fiber, vitamins and various minerals. It is favored by the market for its unique taste and nutritional value. In recent years, with the intensification of China's consumption upgrading trend, pitaya has been introduced to northern areas for facility cultivation. Since this plant is a typical tropical species, it requires an environment temperature of above 15°C for normal growth and development, so it must rely on a greenhouse environment for cultivation in northern China.

[0003] In greenhouse cultivation practice, pitaya plants face special pathological challenges. The inherent high humidity characteristics of the greenhouse environment (usually maintained at 70%-85% relative humidity) meet the plant's tropical growth needs, but also create ecological conditions conducive to the reproduction of pathogenic microorganisms. Among them, anthracnose caused by Colletotrichum gloeosporioides is particularly prominent. These diseases have an incidence rate in the greenhouse environment that is about 40%-60% higher than in open-air cultivation, becoming a key factor restricting the success of northern facility cultivation.

[0004] For disease control, existing technology mainly adopts differentiated treatment strategies: for lesions occurring in branches, lateral stems and other non-trunk parts, the conventional method is to control them by spraying chemical agents on the leaves. Commonly used agents include imidazole and methoxy acrylate fungicides, which can inhibit the spread of surface pathogenic bacteria to some extent through regular spraying. However, when the disease occurs in the main stem of the plant, the existing control technology reveals significant deficiencies: the effect of chemical agent spraying on the control of deep lesions in the main stem is extremely limited. Due to the dense lignified structure and thick epidermal layer of the pitaya main stem, systemic agents cannot penetrate through the surface to reach the infection site deep in the vascular bundle. Actual measurement data show that when the lesion depth exceeds 5mm, the penetration rate of the active ingredients of the conventional spray drug is less than 15%, making it impossible to effectively control deep stem diseases through surface application. This dilemma directly leads to the death of diseased plants, with a mortality rate of more than 65% due to main stem anthracnose, severely restricting the industrial development of pitaya in northern facility agriculture.
