Problems solved by technology

Because the detached leaves inoculated with P. palustris need a certain humidity environment to infect and show symptoms, and the leaves of Apocynum apocynum sampled in the field are easily polluted by other miscellaneous bacteria, causing the leaves to rot rapidly, thus affecting the infection and sporulation effect, and ultimately causing The entire detection is far from reality, and it has also become an important reason for false positives

Embodiment Construction

[0048] The present invention will be further described below in combination with specific embodiments.

[0049] Carrier production: Cultivate apocynum plants in a sterile environment and take their leaves as capture carriers.

[0050]a. Preparation of culture medium: choose commercially available vermiculite with coarser particles and good air permeability. Generally, it is better to choose the vermiculite with a particle diameter of 1-3mm. into the seedling tray.

[0051] b. Pregermination: Select 80-100g of apocynum seeds collected in the same year, disinfect with 0.1-0.5% sodium hypochlorite solution for 3-5 minutes, filter with gauze and rinse with sterile water for 3-5 times. Then put the seeds into a triangular flask, tie the mouth of the flask with a sealing film, and put it in a water bath at 40°C for 12-15 hours to accelerate germination. When the seed buds appear white, pour out the water in the triangular flask.

[0052] c. Colonization: The germinated seeds are ...

Abstract

The invention discloses a method for predicting Apocynum rust caused by Apocynum palisander and a special device for the method. Disease force calculation steps are realized. It can predict more accurately the occurrence of grid rust in field planting of Apocynum apocynum, and then effectively formulate the prevention and control plan. Compared with the prior art, the present invention solves the problem of effectively measuring the number of pathogenic bacteria with infecting ability while measuring the number of pathogenic bacteria, especially solving the problem that the air microbial sampler completes the sampling of the detached leaves of Apocynum apocynum in vitro. The problem of pollution and rot is suitable for the prediction and forecasting of grid rust in field commercial plantation of apocynum.

Description

technical field [0001] The invention belongs to the category of plant disease prevention, and mainly relates to the technology of detecting and forecasting the important disease rust of apocynum apocynum, in particular a method for predicting the rust of apocynum apocynum caused by Pseudomonas spp. and a special device for the method . Background technique [0002] With the growing area and output of Apocynum apocynum, grid rust has become the main disease in Apocynum apocynum plantation, which has an important impact on the growth and quality of apocynum apocynum, especially brings great economic losses to production, and seriously hinders the development of apocynum apocynum. The development of the hemp industry. [0003] The ureterospores of Apocynum palustridium are the source of infection for the occurrence and development of Prussia apocynum. Therefore, accurate determination of the number of uredia spores in the air in the field, especially the pathogenicity, can pro...
