Its geographical location is 01° 06” South latitude and 79° 29”, West longitude located at a height of 120 meters above sea level. The objectives were: Evaluate the effectiveness of the mixture of bioinsecticides and bio-control insects in rice during the rainy season. To study the efficacy of the combination of bio-insecticides and bio-determine the biopesticide and biorregulador more responsive to applying insect control low dose, medium and high and economically analyce the study treatments. The planting material used was the rice variety bioinsecticides INIAP 14, two three doses biorregulators using the experimental design of randomized complete block with a factorial arrangement of 2 x 2 x 2 + 2 with 3 repetitions. All variables were subjected to analysis of variance test was applied and least significant difference (LSD) and Duncan at 95% probability, to determine the statistical difference between treatment means. Based on the obtained results concluded that taller plants were observed when applied Neem manure tea in high doses, up to 5.2 cm in plants receiving chemical insecticide. With application of manure tea Neem mean dose was recorded in plants-highest number of tillers, also showed the lowest percentage of panicle sterility (11.75%) in the applications of snuff, biofertilizer and low dose, the highest yield of grain spraying miss snuff; manure in low dose record 6468 kg/ha. The highest percentage of dead insect (fake miner and soldier) was obtained with the application, high-dose Neem. The effectiveness was mainly reflected in the control of insect soldier when the plants received dose Neem (high and medium) in the false minator favored low dose spray. The combination with manure tea Neem low-dose, medium and high gender minors and grain yields negative marginal utilities. |
