Tridge summary

The Rural Development Administration has warned fall watermelon greenhouse farms about the risk of yellowing virus disease, which can cause symptoms such as yellowing and necrosis on leaves and small fruit size, leading to a significant drop in marketability. The disease is transmitted by cucurbit aphid-borne yellowing virus, melon aphid-borne yellowing virus, and cucurbit chlorosis virus, and can be mistaken for nutrient deficiencies or aging leaves. To prevent the disease, farmers are advised to eliminate virus transmission sources and control vector density by spraying special pesticides regularly.

- Risk of virus infection when vector density increases in August, the time of the first planting - Eliminate virus sources before the first planting, control before vector density increases The Rural Development Administration announced that fall watermelon greenhouse farms that are first planting young seedlings this month should be careful about the occurrence of yellowing virus disease. The viruses that cause yellowing symptoms in cucurbit crops are known to be cucurbit aphid-borne yellowing virus (CABYV), melon aphid-borne yellowing virus (MABYV), and cucurbit chlorosis virus (CCYV) transmitted by whiteflies. As a result of a survey conducted last year on major watermelon farms nationwide, cucurbit aphid-borne yellowing virus was detected in 8.7%, melon aphid-borne yellowing virus in 5.2%, and cucurbit chlorosis virus in 8.5%. When infected with the virus, symptoms such as yellowing and necrosis appear on the leaves, and the fruit does not grow well and becomes small in size. ...
