Systemic insecticides are compounds that may be applied to plants as a foliar spray or to the soil/ growing medium as a drench or granules. These materials are absorbed by roots or into other tissues and then translocated to plant parts. This may then protect plants from damage associated with phloem-feeding insects such as the Hemipterans including aphids, whiteflies, mealybugs, and soft scale...

due to the limited availability of phosphorus in soil especially calcareous soils, it is important to investigate strategies to increase ability of phosphorus uptake by plant. evaluating the effect of zeolite (clinoptilolite), irrigation levels and preferential flows, simultaneously and independently, on increasing phosphorus uptake by corn was objective of this study. potted study was done in ...

The investigation aimed to study the effect of foliar application chemicals on plant canopy, vegetative growth and flowering, as well overall appearance Ixora chinensis plants grown in pot. Application salicylic acid, benzyl adenine silicon at different concentrations significantly influenced growth, pigments compared untreated (control). Plants treated with 10 mg/l 20 acid showed significant i...

In order to study the effects of salinity levels of the irrigation water resulted from the sugarcane field drainage which contained mineral salt (NaCl), four salinity levels (0, 3, 6, 9 ds.m-1) and sugarcane genotypes (C4, C5,C3, CP48-103, C2, CP57-614, CP69-1062) in a potted plant were examined. It was a factorial experiment in randomized complete block design with three replications which was...

Parasitic Maculinea alcon butterflies can only develop in nests of a subset of available Myrmica ant species, so female butterflies have been hypothesized to preferentially lay eggs on plants close to colonies of the correct host ants. Previous correlational investigations of host-ant-dependent oviposition in this and other Maculinea species have, however, shown equivocal results, leading to a ...

Evaluation of the growth Cucumis sativus in arsenic (As) and chromium (Cr) treatedsoils was carried out. Parameters measured were germination, plant height, number ofleaves, relative water content total chlorophyll. The concentrations metalsolutions applied 0, 30, 60, 120 240 ppm saltsseparately. study conducted as potted field experiment. treatments werereplicated four times. Three days after ...
