Ginger Production with Integrated Technologies to Reduce Bacterial wilt Disease in Loei Province

Abstract

          This research has the objective to reduce of bacterial wilt in ginger (Zingiber officinale). Field trials were conducted in Ban Pong Kwang, Pong Kwang Subdistrict, Phu Ruea District, Loei Province, Thailand, from 2022 to 2024. Test method : the soil was sterilized by applying urea at 80 kg/rai mixed with lime at 800 kg/rai (1:10 ratio), broadcast evenly, plowed under, and covered for at least three weeks. The soil was then opened and ridged for planting. Ginger rhizomes were soaked in a suspension of the antagonistic bacterium Bacillus subtilis BS-DOA 24 at 50 g per 20 L of water for 30 minutes prior to planting and spray every 30 days after planting. Remove diseased plants from the plot and sprinkle them with urea mixed with lime in the holes at a ratio of 80:800 Kg/rai. This method was compared with conventional farmer practices under similar environmental conditions. Test results found that, Ginger wilt disease was found to occur in 56% of cases in the the test method and 94% in the farmer’s method. The average yield of the Test method was 7,753 kg/rai, significantly higher than the 5,589 kg/rai obtained by the farmer’s method (p < 0.05). Production costs decreased by 5%, resulting in a 45% increase in net income. These results suggest that this integrated approach can be recommended to ginger growers in Loei Province and similar areas to reduce bacterial wilt and improve production efficiency.
