การลดโรคกาบใบแห้งและการส่งเสริมการเจริญเติบโตของข้าวโดยใช้แบคทีเรียปฏิปักษ์ Thai Agricultural
Patcharaporn Thampiban-udom; Chiradej Chamsawarng; Wanwilai Intanoo.
Rhizobacteria were isolated from rhizosphere soil of rice plants grown in Kanchanaburi Provience. All bacterial isolates were evaluated for the efficacy to inhibit mycerial growth of Rhizoctonia solani, a causal agent of sheath blight on rice by dual culture test on potato dextrose agar (PDA). Six gram positive and three gram negative bacterial isolates effectively inhibited mycerial growth of R. solani by 30.62-75.00 % as compared to the control. Selected bacteria were further tested for the efficacy to promote growth of rice (Chai Nat 1) seedling by seed soaking in bacterial cell suspension (108 CFU/ml) for 24 hr. Soaked seed were incubated for 24 hr before sowing. The results indicated that isolate RRK1 was the most promising isolates that provided the...

ประสิทธิภาพของชีวภัณฑ์เชื้อราไตรโคเดอร์มาปฏิปักษ์สายพันธุ์ 01-52 ชนิดผงแห้งในการเพิ่มผลผลิต และลดโรคเมล็ดด่างของข้าวในสภาพแปลงนา Thai Agricultural
Chiradej Chamsawarng; Wanwilai Intanoo; Rasamee Dhitikiattipong; Phraomas Chareonrak.
Trichoderma harzianum 01-52 prepared as powder formulation was evaluated for the efficacy to reduce dirty panicle and to increase yield of rice. This investigation was the cooperative research between Plant Pathologists from Kasetsart University and Rice Department. Rice seeds (Suphan Buri 3) were soaked in spore suspension of T. harzianum 01-52 (100 g/100 l) for 15 hrs and were further incubated for 24 hrs before sowing in plastic tray contained with burned rice hull. Eighteen-day-old rice seedlings were planted in rice field by transplanting machine. Rice plants were sprayed with T. harzianum 01-52 spore suspension (100 g/100 l/rai or 1,600 m2) for three times at 60, 70 and 80 days after sowing. In some treatments, two additional foliar sprays were...

ประสิทธิภาพของชีวภัณฑ์เชื้อราไตรโคเดอร์มาปฏิปักษ์สายพันธุ์ 01-52 ชนิดเม็ด ในการเพิ่มผลผลิต และลดโรคข้าวพันธุ์ชัยนาท 1 ในแปลงนาที่ไม่ใช้สารเคมีควบคุมศัตรูพืช Thai Agricultural
Chiradej Chamsawarng; Wanwilai Intanoo; Phraomas Chareonrak.
Pellet formulation bioproduct of Trichoderma harzianum 01-52 were evaluated for the efficacy to reduce dirty panicle disease and to increase the yield of rice in non- chemical pesticides using fields in Kanchanaburi province, compared with the Trichoderma untreated control. Rice seeds (Chai Nat 1) were soaked in spore suspension of T. harzianum 01-52 (100 g/100 l) for 24 hrs. The soaked seeds were incubated for another 24 hrs before sowing in the rice field. Rice plants were sprayed with Trichoderma spore suspension (100 g/100 l/rai or 1,600 m2) at 40, 60 and 80 days after sowing. In some treatment, Trichoderma pellets were also used in combination with chemical fertilizer for broadcasting at the rate 10 kg/rai (or 1,600 m2). The results indicated that all...
