How to treat pests and diseases during the flowering period of Cymbidium ensifolium? Detailed explanation of prevention and control methods

In the bright spring month of March, with spring light shining and a hundred flowers competing in beauty, the orchid nursery is full of vitality: the Cymbidium ensifoliumorchidscape has already grown more than 20 cm, and the flower buds are ready to bloom. However, good times do not come, and good flowers are hard to open; the flower buds gradually shrivel. Only after cutting them open did I learn that they had been infested by pests, with stem borers already wrapped inside. For this, the following treatment methods were adopted. ① Turn the orchid pot upside down and rinse the orchid roots with tap water; the inner walls of the leaf sheaths around the pseudobulbs especially must be washed thoroughly; scrape off the dirt, then after drying soak for 30 minutes in a 300-times solution of thiophanate-methyl and carbendazim (the solution should cover above the pseudobulbs), then dry in the shade and repot. ②Cymbidium ensifoliumBefore the diseased plant is repotted, the potting medium and orchid pot must be sterilized at high temperature; cut off the infected leaves, dead tips, and diseased roots. After the orchid plant is repotted, spray pesticide to eliminatepests and diseases. Use litchi pest enemy, buprofezin, thiophanate-methyl, and carbendazim at a 500-times solution for the first spraying, then once every 10 days, for 3 consecutive times. When spraying, spray evenly on the undersides and upper surfaces of the leaves, and especially apply heavily to the pseudobulb parts. ③ Choose a good placement location. Select the best position in the orchid site. The orchid pot should receive direct sunlight before 8:30 a.m. (in summer), then after 9 o'clock be moved into a shade shed to receive dappled sunlight, and after 12 o'clock be placed in a cool place. At this time, it must be well ventilated front, back, left, right, above, and below, and water should be placed on the ground to flow back and increase humidity; when a clear breeze comes gently and a cool breeze blows softly, it is very beneficial to the growth oforchids. Sure enough, hard work pays off. In only 1 month, this pot of Cymbidiumorchidregained its vitality and even sprouted a flower bud. (Guangdong - Li Dengguang)
