In the title compound, C(11)H(18)N(4)O(2) (systematic name: 2-dimethyl-amino-5,6-dimethyl-pyrimidin-4-yl N,N-dimethyl-carb-amate), the pyrimidine ring and dimethyl-amino group are almost in the same plane, making a dihedral angle of 1.6 (1)°. The dihedral angle between the mean plane of the pyrimidine ring and that of the dimethyl-carbamate group is 83.42 (5)°. In the crystal structure, inter-m...

Surface water sampling in 2007-2010 measured the occurrence of carbamates and metalaxyl during base flow conditions and wet weather events in southern Ontario surface waters. Carbaryl, metalaxyl and pirimicarb were the most frequently detected compounds. In 2008 these three compounds were detected in over 50 % of the samples. Overall mean concentrations of carbaryl and metalaxyl over the course...

Mixture toxicity of similar- and dissimilar-acting toxicants can be predicted by the models concentration addition (CA) and independent action (IA) using single substance toxicity data. Knowledge of the toxicants mode of action is thus required in order to use the models. In order to test the predictive capability of the models, we conducted Daphnia magna 48 h immobilization experiments with th...

the toxicity of thiamethoxam and pirimicarb on diaeretiella rapae (mc'intosh) as a parasitoid of lipaphis erysimi (kaltenbach), exposed to residues on glass vials, was investigated under laboratory conditions at 23 ± 2 °c, 70 ± 5% rh and 16:8 h (l: d). moreover, in order to find the negative impacts of both insecticides on the efficiency of d. rapae, the functional response of the exposed paras...

Pesticides stored at or close to the soil surface after field application can be mobilized and transported off the field when surface runoff occurs. The objective of our study was to quantify the potential pesticide losses in surface runoff from a conventionally managed agricultural field in a Swedish climate. This was achieved by measuring surface runoff volumes and concentrations in runoff of...

Most studies on chemical and biological control of arthropod pests of agriculture do not consider the effects of partial host plant resistance. We present research using two partially resistant and a susceptible cultivar of common cabbage (Brassica oleracea var. capitata L.) and determining specific effects of interactions between the host plants, one or two common crucifer aphids (Myzus persic...
