Weed control is an important aspect during the first few years of Christmas tree establishment, as weed competition directly relates to rate growth this time. The objectives study were evaluate efficacy organic mulch and herbicide combinations determine their phytotoxic effects on four different species trees establishment stage: Fraser fir (Abies fraseri (Pursh) Poir), blue spruce (Picea punge...

Abstract The use of organic matter is a highly accepted environmental practice among scientists for the bioremediation polluted soils. In this manuscript we study under laboratory conditions capacity new biostimulant obtained from slaughterhouse sludge in soil by oxyfluorfen at rate 4 l ha −1 (manufacturer’s recommended) over 90-day period. We determined its effects on dehydrogenase, urease, β-...

Abstract The current study aimed to screen glyphosate-alternative weed control methods in three perennial crops Greece. Field trials were conducted and repeated (2018 2019 2020) a citrus orchard ( Citrus clementina Hort. ex Tan), an olive grove Olea europaea L.), vineyard Vitis vinifera L.) under the randomized complete block design (nine treatments, four blocks). Glyphosate was applied (720 g ...

Present study aims to assess the effect of Sublethal dose of the commercial formulations of Cypermethrin (insecticide) and Oxyfluorfen (herbicide). Laboratory study was conducted in a natural Soil and Cow Dung in order to measure effect of these chemicals on activities of stress enzymes viz., Glutathione, Catalase (CAT) and LPO/MDA for a period of 90 days. The activity of Glutathione and CAT wa...

Direct drum seeding has emerged as a viable and alternate substitute to the current transplanted rice address constraints of labor water scarcity well rising cultivation costs. However, heavy weed infestation is main biological factor leading immense yield loss, which requires immediate attention. Therefore, adoption efficient management practice critical for success widespread direct seeded ri...

ABSTRACT The sesame crop has great economic potential due to the various possibilities of exploitation, however, there is a lack information about chemical control weeds in crop, mainly application herbicides pre-emergence. Therefore, objective this study was evaluate viability and efficacy applied pre-emergence for crop. experimental design randomized blocks, with four replications. treatments...

Peroxidizing herbicides were assayed for their capacity to accumulate tetrapyrrole-like compounds in the liquid culture medium when growing the xanthophycean alga Bumilleriopsis filiformis. W e have isolated and purified this compound by H P L C . For identification optical, fluorescence, N M R and mass spectroscopy were employed. All these techniques showed that the accumulation product is pro...
