Comprehensive prevention and control method for anthracnose of potted sword-leaved cymbidium

Abstract

The invention provides a comprehensive prevention and control method for anthracnose of potted sword-leaved cymbidium, belonging to the field of agricultural plant disease control. By aiming at the four growth stages including a leaf-bud budding stage, a bud and young leave growth stage, a flowering stage and a dormancy recovery stage of the potted sword-leaved cymbidium, five prevention and control measures including agricultural prevention and control, plant quarantine, illness monitoring, biological prevention and control, and chemical agent prevention and control are integrally assembled, so that the comprehensive prevention and control measures suitable for each growth stage are provided. The comprehensive prevention and control method for the anthracnose of the potted sword-leaved cymbidium can efficiently control the anthracnose of the cymbidium, obviously reduces number of use and usage amount of pesticide, and has great significance for improving the ornamental value and the economic value of the potted sword-leaved cymbidium and protecting the ecologic environment.

Description

technical field [0001] The invention relates to a comprehensive prevention and control method for potted Jianlan anthracnose, belonging to the field of plant disease prevention and control. Background technique [0002] Jianlan ( Cymbidium ensifolium ) belongs to Orchidaceae (Orchidaceae) orchid genus ( Cymbidium ), is a perennial monocotyledonous herbaceous plant, and is also a precious garden ornamental plant. It has a long history of cultivation in my country. The botanical circle is named after its main place of origin, Fujian. In Fujian, the annual growth period of Jianlan can be divided into leaf bud germination period (March-April), new bud and new leaf growth period (April-May mid-to-late period), flowering period (late May-October), dormant recovery period (November - next March). Leaf bud germination period: As the temperature rises in spring, orchid plants wake up from dormancy, and leaf buds break out of the ground one after another from March to April every ...

Problems solved by technology

Biological control, such as the use of biological pesticides such as trichomycin, agricultural streptoxin, and agricultural anti-Wuyi toxin to prevent and control the spread and prevalence of anthrax bacteria, has the advantages of being non-toxic, harmless, pollution-free, and not easy to produce drug resistance. The disadvantages are Outbreak control of pathogenic bacteria less effective than chemical agents

Chemical control, such as the use of Nadiba (mixed preparation of triclostrobin tebuconazole), 53.8% copper hydroxide, difenoconazole, prochloraz manganese salt, pyraclostrobin, mancozeb ( protective), chlorothalonil (protective), 450 g / L prochloraz emulsion in water, 80% Bordeaux mixture wettable powder, 78% Boer manganese zinc wettable powder and 10% diphenoxylate Cycloconazole water dispersible granules and other chemical agents control the spread and prevalence of anthracnose bacteria; the advantages are quick results, good effects, not limited by regions, seasons and areas, etc., and have good control effects. The disadvantage is that it can kill bacteria at the same time , beneficial organisms are also harmed, destroying the ecological balance, and causing 3R problems

At present, these prevention and control measures have been used in production, but because they have not been effectively integrated and assembled according to the requirements for the prevention and control of anthracnose bacteria in different growth and development stages of Jianlan, the prevention and control effect on Jianlan anthracnose is not good, and there is abuse of chemical pesticides In recent years, anthracnose has become one of the most serious diseases in the planting process of Jianlan.
