Item Open Access Application of Bacillus Thuringiensis through center-pivot irrigation systems for control of Southwestern and European corn borer(Kansas State University, 1980) Nolting, Steven PItem Open Access The merit of corn biological products used in-furrow(2021-08-01) Clark, Allicianitrogen management and how the use of corn biological products used in-furrow at planting can be a sustainable practice for the industry while providing net profit gains for the farmer. Nitrogen is a macronutrient required by corn to produce yields... quality. Biological products have been introduced as an attempt to combat the negative impacts from synthetic Nitrogen fertilizers. Biological products contain living organisms that, when incorporated into soils, increase soil fertility and productivityItem Open Access Present subject matter preparation and future trends in the preparation of high school biology teachers(1967) Santine, Vincent Lee.Item Open Access The academic and professional preparation of the beginning high school biology teachers in Kansas(1964) Rolfs, Ronald Dale.Item Open Access Plant-mediated interactions: considerations for agent selection in weed biological control programs(2014-05-22) Milbrath, Lindsey R.; Nechols, James R.; jnecholsPlant-mediated indirect interactions among herbivores (arthropods and pathogens) are common and extensively reported in the ecological literature. However, they are not well-documented with respect to weed biological control. Such interactions... between biological control agents can have net positive or negative impacts on total weed suppression depending on the strength of the interaction(s), the relative importance of the agent indirectly impacted, and the combined weed suppression that resultsItem Open Access An attitude survey of Junction City High School chemistry students(1967) Watters, Michael William.Item Open Access Comparative evaluation of population effect and economic potential of biological suppression tactics versus chemical control for squash bug (Heteroptera: Coreidae) management on pumpkins(1996-06-01) Olson, D. L.; Nechols, James R.; Schurle, Bryan W.; jnechols; bschurleincome for insecticide-treated pumpkins was substantially lower in 1992 than in 1991. Where biological control and host plant resistance were combined, loss in expected net income in 1992 was considerably less than in 1991. Although costs associated... with biological control were very high relative to the revenues, integrating biological control with host plant resistance may have some potential as an alternative management strategy.Item Open Access The effectiveness of biological control of Frankliniella occidentalis in prevention of the spread of Tomato spotted wilt virus(Kansas State University, 2009-08-11T16:28:02Z) Gillespie, Dianna L.A two-year greenhouse experiment was conducted to compare the relative effectiveness of biological control versus chemical control for western flower thrips, Frankliniella occidentalis, as a means of reducing the spread of Tomato spotted wilt virus... (TSWV) on tomatoes. To compare efficacy of different thrips management tactics for reducing TSWV incidence, tomatoes were subjected to one of three treatments: 1) biological control based on weekly releases of the predatory mite, Amblyseius cucumerisItem Open Access A survey of junior college biology curricula, staffing policy and teacher preparation(Kansas State University, 1975) Blevins, David AItem Open Access A study of practicioners' [sic] ideas on pre-service competencies needed for high school biology teachers(Kansas State University, 1977) Stallings, Mark Anthony
