Influence of Neonicotinoid Insecticides on the Plant Growth Attributes of Cotton and Okra

Management of flatheaded appletree borer (Chrysobothris femorata Olivier) in woody ornamental nursery production with a winter cover crop

“…Imidacloprid, in particular, is an effective control of FHAB damage and the insecticide can persist in the plants for two or more years, allowing growers to treat once for a multiyear production cycle . In many cropping systems, the use of imidacloprid is positively correlated with plant growth . Similarly, in our study during the first year we found that height, diameter and canopy size increased due to the application of insecticides, especially in the bare rows.…”

“…The effect of imidacloprid on plant growth parameters were reported as a phytotonic effect . However, this system of phytotonic effects was mostly investigated field crops like okra and cotton. Similarly, the effect of imidacloprid on red maple plant growth parameters was inconsistent over the two years of replication in our research, and thus imidacloprid cannot be recommended as a plant growth‐enhancing agent in red maple production system.…”

Conservation tillage and thiamethoxam seed treatments as tools to reduce thrips densities and disease in cotton and peanut

“…Similarly, differences between cotton and peanut responses to neonicotioid seed treatments may indicate a difference in the physiological responses to the seed treatment. Preetha and Stanley (2012) demonstrate that thiamethoxam can affect cotton growth. There is no literature available regarding the effects of that compound on peanut growth in the absence of thrips pressure.…”

“…Faircloth et al (2001) showed that thrips feeding damage can reduce cotton biomass and some of the increase in plant height and leaf count may be due to a release from thrips pressure. However, neonicotinoid seed treatment alone is reported to produce an increase in seedling plant height independent of insect pressure (Preetha and Stanley, 2012). Sadras and Wilson (1998) observed decreased leaf area in thrips infested cotton.…”

Direct effects of insecticides on common ragweed-implications for natural enemy exclusion trials

“…8) Other studies, in contrast, found positive effects of insecticides through enhanced root development, plant growth, or physiological activity, sometimes resulting in increased yield. 9,10) The application of carbofuran, a systemic carbamate, increased yields and biomass of several crops including watermelon, pea, tobacco and corn, because the metabolites of this molecule promoted crop growth and inhibited the activity of indole acetic acid oxidase. 5) Treatments with chlordimeform, a formamidine insecticide, and imidacloprid, a neonicotinoid insecticide had similar positive direct effects on cotton growth.…”
