Common Watermelon Peperomia Pests and diseases. Survival and spread Therefore, watermelon crops planted in fields with both root-knot nematode and the Fusarium fungus may face yield losses greater than the losses from either disease alone. The disease progress curves of black root rot in watermelon after inoculation with M. incognita and/or D. sclerotioides indicated that co‐inoculation of these agents did not increase or decrease disease severity caused by single‐inoculation of D. sclerotioides (Fig. Use resistant varieties and seed … It is possible that the root knot nematode may increase infection of Fusarium wilt. Affected plants were often wilted and slower growing than healthy plants. The root-knot nematode occurs primarily in sandy soils. 1 Effects of wheat straw addition on the disease incidence ( a ), disease symptoms score ( b ), root length ( c ) and plant height ( d ) of monoculture watermelon at different times points. Brown vascular discolouration inside infected stem or root leads to the death of plants. They found a wide diversity in root … Therefore, crop rotation is not an effective management strategy. In this study, efficacy of some seaweeds and asafoetida were evaluated in field plots on watermelon and eggplants in suppressing the soilborne diseases and their effect on plant growth. possible that the root knot nematode may increase infection of Fusarium wilt. However, scientific reasons are still unclear. Watermelon grows as a vine that sends out long runners along the ground. Cucurbits include watermelons, cantaloupes, cucumbers, zucchini, pumpkins, squash, bitter melons, gourds, and hairy melons. These results showed that wheat straw reduced the disease incidence of monoculture watermelon, and promoted watermelon growth, and it was no correlated with the amount of wheat straw addition. Diseases are common and can prevent watermelon quality and supply. Diseases of Watermelon Disease name Caused by Prevention Damping-off Fusarium spp Good cultural practices and seed treatment Root-knot Nematodes worms use nematicide & fumigants Gummy Stem Didymella bryoniae Good cultural practices and seed treatment Anthracnose Glomerella cingulata Use resistant varieties Downy Mildew Pseudoperonospora cubensis. The experiment was also conducted at farmer’s field on watermelon. CHARLESTON, SOUTH CAROLINA, June 25, 2019—A new watermelon line, developed by Agricultural Research Service and Clemson University scientists, gets to the root of the problem of a major disease and pest of watermelon crops in the southern United States.. Carolina Strongback is a rootstock watermelon … 1 Pre-plant soil fumigation with nematicidal fumigants, such as 1,3-dichloropropene (Telone ® II) and metam sodium (Vapam ® HL TM Soil Fumigant), can effectively reduce populations of root-knot nematodes and control the disease. As discussed earlier, the watermelon plants observed were infected both with Fusarium wilt and root knot nematode. Watermelon Growth Diseases.
