  • From our field investigation from 2017 to 2018, five diseases and four insect pests have been identified as the primary biotic stressors of fruit-producing mulberry, which include popcorn disease and mulberry sucker, respectively. In this study, we examined the relative control effects of selected agro-chemicals against the popcorn disease and mulberry sucker. Our systemic treatment methods to simultaneously control the popcorn disease and the mulberry sucker indicated that an integrated control method showed a superior result with the control efficacy of 89.3%, while a conventional control method resulted in 66.7%. As a result, we concluded that it is much efficient to control both disease and insect pest in mid-April while sequentially applying chemicals only for the popcorn disease from February. By considering the ecological aspects of the popcorn disease and mulberry sucker, this systemic treatment will be able to reduce the labor of growers required for the control.

  • Author investigated the control measure and the life cycle of the mulberry sucker, Anemoneura mori Schwarz. The results are as follows; 1. It is clear that the life cycle of mulberry sucker is one generation a year, but not obvious about the duration of pupa. 2. Even though various insecticides were used for control, they are not of a practical value during the egg stage. It is, however, believed that the mulberry sucker, when become larvae, can be controlled by spraying about 400 litres per 1 tanbo( DDVP, 1000$\times$). 3. Author recommends the control measures which you may use not only an insecticide, but also cut off branches so as to make leaf get enough sunlight and ventilation.

  • BACKGROUND: Two Field tests were conducted at Buan and Yangpyung in 2012 and 2013 to confirm controlling effect of mulberry popcorn disease and mulberry Sucker pests which are becoming serious in mass cultivation area of eco-friendly farming mulberry. METHODS AND RESULTS: As the treatments, 4 Natural products and 3 microbials were applied and 4 mulching materials were used. On the prevent effect of mulberry popcorn disease(Sclerotinia shiraiana) by using mulching materials, nonwoven fabric mulching showed worse effect than non-mulched treatment plot. Moreover, rice straw mulching showed significantly worse effect compare to nonwoven fabric and herb mulching treatments. Natural plant extracts and microbials showed 40~65% control value in 2013, which is little bit worse than 2012 results. On the control effect of mulberry Sucker(Amomoneura mori), organic products which combined with neem, sophora and derris showed excellent result as similar control level of Thiophanate-methyl. It means the chemical products can be replaced with organic product. CONCLUSION(S): According to the 2 years studied results, integrate eco-friendly farming measures are recommended for control of mulberry popcorn disease, because any single method is seemed not sufficient enough. However, natural plant extracts mixture is recommended as a product to control of mulberry Sucker.

  • Seasonal occurrence and tne effects of two organic farming materials on mulberry sucker, Anomoneura mori were investigated on mulberry grown for fruit production in Buan, Jeonbuk, South Korea.. Overwintered adults of A. mori occurred from late March to mid-May with a peak in mid-April. Overwintered females began to lay eggs on winter buds from mid-April. Emerged nymphs appeared from early May and peaked in mid-May. Newly eclosed adults, appearing from early June, soon scattered and were not found in the mulberry field after mid-June. Therefore, the optimal control period for A. mori was mid-April for adults and early May for nymphs. Sophora extract and derris extract were effective organic farming materials for controllingl the nymphs of A. mori. It was found that derris extract sprayed 2-3 times at 5-days intervals in early May effected good control against A. mori nymphs.
