Abstract

The issues of improving the quality of application of fungal and bacterial biological products when applying the flow rates of working fluid up to 20 L/ha are considered. Along with the traditional methodology for assessing the quality of applying the working fluid of biological products to the treated surface, a new method for evaluating the effectiveness of applying biological products was also used, which consisted in selecting a certain area of the potato leaf surface by plant tiers 1 day after processing to determine the viability of fungal and bacterial products with low-volume (LV) and ultra-low-volume (ULV) spraying technologies. When applying the technology of spraying up to 10 L/ha, despite the high coating density, the cells of microorganisms fall on the leaf surface with an insufficient amount of liquid for their active reproduction on the treated surface. In addition, at low humidity, due to the rapid evaporation of droplets from the surface of the treated leaves, microorganisms do not multiply and are carried away by the wind when drying. The conducted research tests of the use of the mushroom biological product Trichocin at a consumption rate of 20 L/ha on test objects (potato plants of the Galla and Riviera varieties) using especially pure glycerin and the moisture-retaining food additive sorbitol as antivaporizers showed that their use ensured the viability of the cells of the biological product and the high rate of their reproduction on the treated surface due to moisture retention.

植保生物制品应用技术的改进

摘要

考虑了当工作液流量高达20 L/ha时提高真菌和细菌生物制品的施用质量的问题。除了评估将生物产品工作液施用于处理表面的质量的传统方法外，还使用了评估施用生物产品有效性的新方法，该方法包括选择马铃薯叶表面的特定区域处理后 1 天对植物进行分级，以确定采用低容量 (LV) 和超低容量 (ULV) 喷雾技术的真菌和细菌产品的活力。当采用高达10升/公顷的喷雾技术时，尽管涂层密度很高，但微生物细胞落在叶表面，液体量不足以在处理过的表面上进行活跃繁殖。另外，在低湿度下，由于处理过的叶子表面的水滴迅速蒸发，微生物不会繁殖，干燥时会被风带走。使用特别纯的甘油和保湿食品添加剂山梨糖醇作为防蒸发剂，以 20 升/公顷的消耗量对测试对象（Galla 和 Riviera 品种的马铃薯植物）使用蘑菇生物产品 Trichocin 进行的研究测试表明它们的使用确保了生物产品细胞的活力以及由于保湿而在处理过的表面上的高繁殖率。
