A field experiment was carried out to test the efficacy of insecticides against aphid Aphis craccivora in fenugreek at Research Farm, Agricultural Station, Mandor-Jodhpur during rabi, 2021-22. After two sprays, flonicamid 50 WG found most effective while azadirachtin 10,000 ppm (4.73 aphids/5 cm central shoot) treated plots least effective. Maximum yield (1722 kg/ha) obtained from with WG. The ...

The effects of azadiraehtin A , given oral ly, on the reproduct ion of mature females of Rhodnius prolixus were studied. Azadiraeht in A caused a reduction in oocyte growth and consequently in the egg product ion in a dose-dependent manner. Eggs layed had no alteration in their viabil it ies. A significant correlat ion between these effects and the titers of both vi tel logenin in the haemolymp...

The joint action of destruxins and three botanical insecticides, rotenone (Rot), azadirachtin (Aza) and paeonolum (Pae) against the cotton aphid, Aphis gossypii, was bioassayed. In laboratory experiment, several synergistic groups of destruxins with botanical insecticides were found by means of Sun's Co-toxicity Coefficients (CTC) and Finney's Synergistic Coefficient (SC). The best synergistic ...

The nitrates produced after mineralization from compost may be prone to leaching, especially in tropical sandy soils, because of the increased rate nitrification and porous nature such soils. This result low nitrogen (N) use efficiency adverse environmental effects. Inorganic inhibitors are costly mostly unavailable Ghana. Research on simple but effective local materials for as is therefore a p...

Background: Melia indica and M. azedarach (Meliaceae) are widely used in traditional medicine. These species are considered as natural pesticides. Their major compound is azadirachtin (AZD) which is considered as the marker for quality control of these species. Objective: In the present investigation, AZD content of the leaves and fruits (comprising the whole fruit, peel, pulp and seeds) of M....
