Philippines Los Banos BIOLOGICAL CONTROL Jeff C. Ebio G-1L INTRODUCTION Farmers sure aim to have abundant and healthy agricultural produce but that became so elusive as the prevalence of disease-causing fungi or bacteria and defective planting materials remain a challenge. To cease all these through a necessary and effective pest management and disease control schema must be utilized. Using chemical pesticide would be a usual resort though as it brings

Topical microemulsion systems for the antifungal activity containing Clotrimazole are designed to overcome the problems associated with its low solubility (0.49 mg/L) and slow dissolution in aqueous solutions. In this study‚ Clotrimazole was incorporated in jambhul honey microemulsion formulation without causing instability of the emulsion. The solubility of Clotrimazole in various oils‚ surfactants and cosurfactants was assessed to finalize the components of the w/o and o/w microemulsions. The pseudoternary

hormonal signal that inhibits shoot branching in plants has long escaped identification. Strigolactones are compounds thought to be derived from carotenoids and are known to trigger the germination of parasitic plant seeds and stimulate symbiotic fungi. Here we present evidence that carotenoid cleavage dioxygenase 8 shoot branching mutants of pea are strigolactone deficient and that strigolactone application restores the wild-type branching phenotype to ccd8 mutants. Moreover‚ we show that other

Some Ways That The Environment Affects Human Health? Air Pollution Air pollution is one obvious environmental health threat in OECD countries‚ contributing to a number of illnesses‚ such as asthma and in some cases leading to premature death. Of particular concern is the fact that children are more vulnerable to air pollution than adults‚ and increased rates of infant mortality have been recorded in highly polluted areas. Concerns about the impact of air pollution on health and the economy
