Trimurti Hesti Wardini
The rate of tuber damage caused by Cylas is assessed based on the intensity of Cylas attacks, and is considered to be 5 levels as follows. Cylas insects are endemic pests in the sweet potato in the village of Cigendel. When introduced to Cylas, the intensity of cylas infection increases. Tagetes presence can reduce the intensity of cylas infection. The micro climate can also affect the intensity of cylas infection. Based on the results obtained, the model that we submitted in controlling Cylas infection using bio-insecticides is to plant tagetes around 1 month sweet potato plant plots after the seeds are planted. However, Tagetes should not be planted in the pematang on the ground. Bibit sweet potato is planted with a depth of about 5-10 cm and a distance of 25 cm. Bibit Tagetes was planted one month after the sweet potato planting. Tagetes are planted on all sides of sweet potato plants, with a spacing of around 15 cm. Observation of Cylas infestations and the level of sweet potato damage is carried out 2 weeks after the introduction of cylas then every 1 month to harvest. Plant samples are taken randomly by 5 plants / plots. Micro climate data is obtained by measuring temperature and moisture using psychrometer slings, light intensity using Lux Meter, pH using soil tester.
