A new spot test has been developed for the detection of dithiocarbamate fungicides such as mancozeb, propineb and zineb at nkg level in soil and water. The colour formation is based on the decomposition of dithiocarbamate to carbon disulphide which reacts with plumbite i ' alkaline medium to form a brown complex that finally converts to black lead sulphide. The coloured product exists as a brig...

The pathogen Phytophthora capsici, which causes black pepper foot rot, is the most detrimental disease that affects productivity and lowers qualitative quantitative spike yields in southwest Ethiopia. effectiveness of several fungicides cultural methods against capsici was tested a field experiment. Five commercial practices were examined, natural infection noted. Disease incidence determined b...

An experiment was carried out at Chaudhary Charan Singh Haryana Agricultural University, Hisar during the year 2019-20 to study effect of different fungicides and calcium nitrate on quality shelf life Kinnow mandarin”. A spray carbendazim, copper oxychloride, mancozeb, propiconazole, nimbecidine, nitrate, their combinations were done ten days prior harvesting years old plants. When compared fru...

Bacterial spot of tomato (BST) is a disease that severely afflicts crops, especially in geographic areas such as the Southeastern U.S., where environmental conditions favor rapid development. Farmers usually use chemical treatments copper–mancozeb mixtures and acibenzolar-S-methyl, among other methods, to manage BST. However, these generally fail improve marketable yields, thus raising question...

Major loss in crop yield and quality are due to biotic stresses known to be a major threat to agriculture. During the past few decades, pesticides have been used frenziedly though, it is not a good measure of sustainable practice. Microalgae easily become the first, in the list of nontarget organisms that are affected by pesticides. The present study provides the first information about the eff...

Pyraclostrobin 25%EC at., 50, 75 and 100ga.i/ha, was evaluated for two seasons against early blight of tomato cultivar NS2535. The efficacy of pyraclostrobin was compared with commonly used chemicals viz., captan, mancozeb and an untreated control. Phytotoxicity effect of pyraclostrobin was evaluated using a single spray, at concentrations of 100, 200 and 400gm a.i/ha Pyraclostrobin at all conc...

Thyroid disease is common, and evidence of an association between organochlorine exposure and thyroid disease is increasing. The authors examined the cross-sectional association between ever use of organochlorines and risk of hypothyroidism and hyperthyroidism among female spouses (n = 16,529) in Iowa and North Carolina enrolled in the Agricultural Health Study in 1993-1997. They also assessed ...

BACKGROUND An evaluation was made of the effects of seven neurotoxic insecticides (esfenvalerate, indoxacarb, clothianidin, thiacloprid, azinphosmethyl, phosmet and imidacloprid), one insect growth regulator (novaluron) and two fungicides (myclobutanin and mancozeb), with water as the control, on the horizontal mobility of plum curculios exposed to dried pesticide residues. Mobility was recorde...
