Embodiment 1

[0032] A 30-acre orchard in a certain district of Guangzhou City, Guangdong Province, was planted in the spring of 2012. Due to the diseased seedlings, canker broke out in the summer of 2013 during the fruit-hanging period, and the phenomenon of fruit peeling was serious, with the peeling rate reaching about 60%, and the economic benefit was poor. In the autumn of 2013, the pitaya canker comprehensive prevention and control method of the present invention was adopted, and the agricultural operations were strictly carried out according to the method of the present invention, as follows.

[0033] A kind of comprehensive prevention and control method of pitaya canker:

[0034]1) On the ground at the entrance of the orchard, sprinkle a lime strip about 1 meter (0.8-1.2m) wide every year to reduce the spread of pathogenic bacteria through the movement of people and human factors.

[0035] 2) The diseased orchard focuses on prevention, combined with chemical control. Different con...

Embodiment 2

[0046] A 40-acre orchard in a certain district of Haikou City, Hainan Province, started planting in May 2013. In mid-July of that year, sporadic small spots with a diameter of 0.5-2 mm faded and depressed on the newly sprouted shoots. Timely and effective prevention and treatment. In June 2014, the fruit began to bear fruit, and the canker lesions on the young shoots increased, and the area of ​​the lesions on the stem surface reached 45%, and the disease level was 4. The fruit is also endangered, and there are many flowers and fruits, and the flower skin rate reaches more than 50%, which seriously reduces the commodity value of the fruit. In the autumn of 2014, the pitaya canker comprehensive prevention and control method of the present invention was adopted, and agricultural operations were strictly carried out according to the method of the present invention.

Embodiment 3

[0057] A newly-built orchard of 20 mu in a certain district of Nanning City, Guangxi Zhuang Autonomous Region, was planted in the spring of 2014. Before planting, select pest-free seedlings for cultivation, so as to cut off the spread of pathogens from the source. Agricultural operations are carried out strictly according to the method of the present invention.

[0058] A kind of comprehensive prevention and control method of pitaya canker:

[0059] (1) To build a new orchard, select pest-free seedlings for cultivation, and cut off the spread of pathogens from the source;

[0060] (2) On the ground at the entrance of the orchard, sprinkle a lime strip about 1 meter (0.8-1.2m) wide every year to reduce the spread of pathogenic bacteria through the flow of people and human factors;

[0061] (3) The orchard without disease mainly focused on prevention, and different preventive measures were adopted in different seasons, and the lowest dose of medicine was used. All the agents ...

Abstract

The invention discloses a comprehensive control method for a dragon fruit canker, and belongs to the technical field of plant protection and fruit culture. The method comprises the steps that for a newly-built orchard, the disease-free nursery stock and disease-resistant variety are selected to be cultivated; a bactericide is sprayed in spring in the morbidity orchard to restrain germination of pathogen spores; summer is the key control period, the phenomenon that pathogenic bacteria circularly infect a medium is reduced by cut off novel tender branches in time, and bactericide is sprayed; clipping, orchard cleaning and medicament spraying are performed in time in autumn and winter, and a pathogenic spore hibernacle is removed. All medicaments are organic silicone additives, the medicaments are promoted to extension and absorption on the surfaces of branches, and the control effect is enhanced. By implementing the comprehensive control method for the dragon fruit canker, damage to the canker can be completely controlled for the morbidity orchard, and the good prevention effect can be achieved for a non-attacked orchard.

Description

technical field [0001] The invention relates to pitaya canker, in particular to a comprehensive prevention and control method for pitaya canker, belonging to the technical fields of plant protection and fruit tree cultivation. Background technique [0002] Dragon fruit originates in Mexico, Central and South America, and is distributed in tropical and subtropical regions. In the mid-to-late 1990s, it was successively planted in Guangdong, Guangxi, Guizhou, Fujian, Hainan and other provinces, and gradually became one of the important economic crops for farmers to increase their income. With the further expansion of planting area, diseases in dragon fruit producing areas are becoming more and more serious. [0003] The climate characteristics of high temperature and humidity in summer in tropical and subtropical regions are also very prone to the occurrence of pathogenic fungi. Pitaya canker was found in the western part of Guangdong Province in 2004, and the occurrence of t...
