chlormequat (cycocel or ccc), the plant growth retardant, was evaluated for its ability to control plant height in brassica oleracea cultivar ‘kamome white’ and ‘nagoya red’. different concentrations of ccc (0, 500, 1000 and 1500 mg/l) were sprayed and drenched on plants 40 days after transplanting. data were recorded the 60 and 90 days after transplanting. the 1500 mg/l of ccc resulted in abou...

OBJECTIVE To determine the risk of external urogenital birth defects (UGBDs) in newborn boys from a malarial area currently sprayed with technical 1,1,1-trichloro-2,2-bis(4-chlorophenyl) ethane (DDT), as increased fetal oestrogenic or anti-androgenic exposure might be involved in the pathogenesis of increased prevalence of human male reproductive tract anomalies, and DDT and metabolites interac...

Filamentous viruses are common in nature and efficiently deliver - sometimes via aerosol - genetic material, viral proteins, and other factors to animals and plants. Aerosolization can be a severe physicochemical test of the stability of any filamentous assembly whether it is made from natural polymers such as viral proteins or synthetic polymers. Here, worm-like "filomicelles" that self-assemb...

Pesticides are essential for agricultural and horticultural crops production. Pesticides are commonly classified as insecticide, fungicide, herbicide, rodenticide, etc. These pesticides act against insects, rodents, weeds which are harmful in agricultural or horticultural planting. Normally, farmers use the pesticides following the instruction written in the package. In most cases, the pesticid...

Esteya vermicola (Ophiostomataceae) is an endoparasitic fungus that has great potential as a biological control agent against the pinewood nematode Bursaphelenchus xylophilus which causes pine wilt disease. We tested E. vermicola for control of pine wilt disease by spraying E. vermicola conidia on artificial wounds on pine seedlings, and the optimum E. vermicola treatment density and applicatio...
