Efficacy of some insecticides (pymetrozine 50WG, sulfoxaflor 24SC and imidacloprid 17.8SL) was evaluated against rice white backed plant hopper (WBPH) Sogatella furcifera Horvath. Sulfoxaflor @218.7 g a.i./ ha pymetrozine 50WG @ 187.5 gave significantly results (7.57 7.82/ hill, respectively).However, highest grain straw yield (40.87 64.33 q/ ha) observed with 50WG@ 218.7 (40.41 64.22 ha). Rega...

Relatively few studies have investigated potential interactions of host plant resistance and insecticides for insect control. To examine possible interactions, host plant resistance was measured independently for four tomato cultivars and one wild tomato accession against tomato psyllids, Bactericerca [Paratrioza] cockerelli [Sulc] (Homoptera: Psyllidae). Plant lines tested included the commerc...

The title compound, C10H11N5O {systematic name: 6-methyl-4-[(E)-(pyridin-3-yl-methyl-idene)amino]-4,5-di-hydro-1,2,4-triazin-3(2H)-one}, C10H11N5O, is used as an anti-feedant in pest control. The asymmetric unit comprises two independent mol-ecules, A and B, in which the dihedral angles between the pyridinyl and triazinyl ring planes [r.m.s. deviations = 0.0132 and 0.0255 ] are 11.60 (6) and 18...

Oligosaccharides have been used for an environmentally friendly insect control in the agricultural industry. In order to discover novel eco-friendly pesticides, a series of partially acetylated oligorhamnoses mezzettiasides, 2-8, and their analogues, 9-14, with biosurfactant characteristics were designed and synthesized, some of which exhibited comparable to or even stronger aphicidal activity ...

abstract in a laboratory study the effect of three insecticides (pirimicarb, pymetrozine and spinosad) was evaluated on aphelinus mali a parasitoid of woolly apple aphid. to investigate the contact effect, adults were caged for 16 hours in petri-dishes containing apple leaves sprayed with each insecticide. to determine the oral toxicity in the same period of time, other petri-dishes containing ...

t g a 1 a c w ( a e c a e The compatibility of five insect growth regulators (IGRs), buprofezin, pyriproxyfen, fenoxycarb, pymetrozine, and kinoprene, were tested in the laboratory for compatibility with the whitefly parasitoid Eretmocerus eremicus Rose and Zolnerowich (Hymeoptera: Aphelinidae). The survivorship of adult paraitoids foraging on poinsettia leaves with residues 6, 4, and 96 h of a...
