Abstract

The stem borer (Ostrinia furnacalis Guenee) is one of the main pests of corn. The yield loss due to this pest attack reaches 20-80%. These pests are generally controlled chemically, causing various negative effects from the results of control, therefore environmentally friendly control techniques are needed, such as the use of bio-compost and bio-LOF. Bio-compost is compost combined with a consortium of bacteria Serratia marcecens, Bacillus thuringiensis and Pseudomonas fluorescens. Bio-LOF is a liquid organic fertilizer that is processed using cow feces, cow urine, Glicerida leaves and coconut husk. The research objective is to determine the effectiveness of bio-compost with several concentrations of bio-LOF to control stem borer pests in sweet corn. The research was conducted at experimental land of Payakumbuh Agricultural Polytechnic from January to June 2020. This study used a factorial completely randomized design (4x3) with 3 replications. Factor K, namely K1; Tithonia bio-compost, K2; Hay bio-compost. K3; Manure bio-compost. K4: without bio-compost. Factor D are: D1; Bio-LOF concentration 30%, D2; Bio-LOF 20%. D3: without Bio-LOF. The data obtained were analyzed for variance using a statistical program of 8.0, then continued with the dancun test α 5%. The results showed that the three types of bio-compost combined with bio-LOF could reduce the percentage of O. furnacalis pest attack on the stems and tips of sweet corn cobs. There were 5 treatment combinations with very effective criteria for coefficient of relatively control (CRC), namely. Tithonia bio-compost, Bio-LOF 30%, Hay bio-compost, bio-LOF 30%, chicken feces bio-compost, bio-LOF 30%, Straw bio-compost, Bio-LOF 20%, Without bio-compost, Bio-LOF 30%. The concentration of bio-LOF sprayed on the stems and leaves affects the effectiveness of the control where the 30% bio-LOF concentration had the very effective criteria of control, while the 20% concentration had the effective criteria of control.

生物堆肥和生物poc对甜玉米突袭虫

玉米螟(Ostrinia furnacalis Guenee)是玉米的主要害虫之一。这种害虫造成的产量损失达20-80%。这些害虫一般采用化学方法防治，防治结果会产生各种负面影响，因此需要采用环境友好型防治技术，如使用生物堆肥和生物有机肥。生物堆肥是混合了沙雷氏菌、苏云金芽孢杆菌和荧光假单胞菌的堆肥。Bio-LOF是一种用牛粪、牛尿、甘油三酯叶和椰子壳加工而成的液体有机肥。研究目的是确定不同浓度的生物堆肥对甜玉米螟虫害虫的防治效果。该研究于2020年1月至6月在Payakumbuh农业理工学院的实验地进行。本研究采用因子完全随机设计(4x3)，共3个重复。因子K，即K1;Tithonia生物堆肥，K2;干草bio-compost。K3;肥料bio-compost。K4:不含生物堆肥。因子D为:D1;Bio-LOF浓度30%，D2;Bio-LOF 20%。D3:无Bio-LOF。使用8.0的统计程序对所得数据进行方差分析，然后继续采用α 5%的丹村检验。结果表明，3种生物堆肥与生物有机肥配合施用，可降低甜玉米芯茎尖上灰蚜的侵染率。有5种治疗组合具有非常有效的相对控制系数(CRC)标准，分别为。Tithonia生物堆肥，Bio-LOF 30%，干草生物堆肥，Bio-LOF 30%，鸡粪生物堆肥，Bio-LOF 30%，秸秆生物堆肥，Bio-LOF 20%，无生物堆肥，Bio-LOF 30%。茎叶喷施生物lof的浓度影响防治效果，其中30%的生物lof浓度具有非常有效的防治标准，20%的生物lof浓度具有有效的防治标准。
