摘要

在NARDI Fundulea,作者集体介绍了在玉米种子(Olt品种)上施用的两种杀虫剂Gaucho 600 FS (8.0 l/吨)和Nuprid 600 FS (8.0 l/吨)以及在植被上施用的两种杀虫剂Calypso 480 SC (90 ml/公顷)和Decis Mega (150 ml/公顷)对玉米叶象鼻虫攻击的效果。还在布加勒斯特农业学院植物科学系产量质量实验室进行了生产力要素和种子产量和化学成分的测定。施用Nuprid 600 FS和Calypso 480 sc时的药效波动较大,分别为4.56和8.33。未施用杀虫剂的控制区所录得的药效最大。用两种杀虫剂处理种子,植株密度在116 ~ 118株/块之间,分别超过65%。在植被上喷洒杀虫剂效果不显著,Calypso 480 SC为31株/畦,节约17%;Decis Mega为16.75株/畦,节约9.31%。品种产量最高,可达7778 kg/ha,最佳药效和密度为65690株/ha。在收获时,杀虫剂对种子的化学成分没有影响。但由于高温和干旱,玉米种子积累了12.31%的蛋白质;70.18%的淀粉;5.05%的石油;1.46%灰;5.24%的纤维。

The Insecticides Effectiveness on Tanymecus Dilaticollis Attack on Maize at NARDI Fundulea

In this paper, authors collective present effect of two pesticides applied on maize seeds (Olt variety), Gaucho 600 FS (8.0 l/tonne) and Nuprid 600 FS (8.0 l/tona) and two insecticides applied in vegetation, Calypso 480 SC (90 ml/ha) and Decis Mega (150 ml/ha) against maize leaf weevil attack, at NARDI Fundulea. Also, it performed productivity elements and seeds yields and chemical compozition on Laboratory of Yields Quality of Plant Science Department, Bucharest Faculty of Agriculture. The higher insecticides effectiveness fluctuated between 4.56 when it was applied Nuprid 600 FS and 8.33 when it was applied Calypso 480 SC.

The largest attack was recorded to control plots where there is no treatment was applied. The density of plants ranged between 116 and 118 plants/plot, respectively over 65% of saved plants by treatment on seeds with both insecticides. In case of spraying insecticides in vegetation, their effect were insignificant, 31 plants/plot density and 17% saved plants in case of Calypso 480 SC and 16.75 plants/plots density and 9.31% saved plants in case of Decis Mega. The largest yields was of 7,778 kg/ha at insecticides variant with the best effectiveness and density of 65,690 plants/ha. Insecticides showed no influence on chemical composition of seeds at harvesting. But due to high temperatures and drought, the maize seeds accumulated: 12.31% protein; 70.18% starch; 5.05% oil; 1.46% ash; 5.24% fibre.
