Agricultural solid waste (corn cob) has been investigated asbiosorbent for removal of metribuzin herbicide from aqueous solution. Parameters influencing extraction efficiency such as pH of the sample, contact time of sample with biosorbent, shaking time, temperature, heating time, sorbent dose were studied. Maximum sorption of metribuzinwas found at pH 5.0. The sorption of metribuzin on corn co...

The addition of organic manure affects the biological, chemical and physical properties of soil that control the fate of herbicides. Three dinitroaniline herbicides were studied to asses their persistence, dissipation and residue management in sandy loam soil with and without addition of farmyard manure (FYM) under middle western Indian agro-climatic conditions. The herbicides, pendimethalin [N...

Tiphia vernalis Rohwer is a hymenopteran ectoparasitoid of Japanese beetle, Popillia japonica Newman, larvae. The adult wasps feed on nectar or honeydew between mid-April and late June. Adults may contact pesticides when landing on foliage or when females hunt for grubs in the soil. The lethal effect of nursery, turf, and landscape pesticides was determined by exposing wasps to treated foliage ...

A primary concern with composting is the lack of knowledge about the fate of widely used pesticides. Also, there is increasing interest in the use of composting as a bioremediation method for soils contaminated with xenobiotics such as TNT, PCBs, chlorophenols and PAHs. We used a laboratory scale composting system to determine the extent of mineralization, incorporation into humic matter, and v...

Greenhouse studies were conducted in 2008-2009 with the objective of adjusting dose-response curves of the main soil-applied herbicides currently used in cotton for the control of Amaranthus viridis, A. hybridus, A. spinosus, A. lividus, as well as comparing susceptibility among different species, using the identity test models. Thirty six individual experiments were simultaneously carried out ...

The effects of nematicides carbofuran (C) and fenamiphos (F) and herbicides metribuzin (M) and trifluralin (T), alone and in combination, on hatching, penetration, development, and reproduction of Meloidogyne incognita race 3 were determined under laboratory conditions. To study hatching, entire egg masses were exposed to nematicides (6 mug/ml), herbicides (0.5 mug/ml), and their combinations o...

Zarzecka K., Gugała M. (2018): The effect of herbicides and biostimulants on sugars content in potato tubers. Plant Soil Environ., 64: 82–87. The objective of the present work was to determine changes in total sugars, reducing sugars and sucrose content in potato tubers under conditions involving an application of biostimulants and herbicides. Research material included table potato tubers obta...
