The title compound, C23H32N2OS, is a thio­urea-based insecticide. The dihedral angle between the phenyl ring and the diisopropyl benzene ring plane is 73.18 (6)°, while that between the plane of the thio­urea group and the diisopropyl benzene ring is 86.00 (5)°. Disorder was modelled for the S atom and the two methyl C atoms of the isopropyl group over two sets of sites with an occupancy ratio of 0.742 (4):0.258 (4). In the crystal, N—H...S hydrogen bonds link adjacent mol­ecules, forming R22(8) inversion dimers that pack into chains along the b-axis direction.

The title compound [systematic name: 4,6-di­chloro-N-(2-chloro­phen­yl)-1,3,5-triazin-2-amine], C9H5Cl3N4, is a triazine fungicide. The dihedral angle between the planes of the triazine and benzene rings is 4.04 (8)°. In the crystal, two weak C—H...N hydrogen bonds and short Cl...Cl contacts [3.4222 (4) Å] link adjacent mol­ecules, forming two-dimensional networks parellel to the (112) plane. The planes are linked by weak inter­molecular π–π inter­actions [3.6428 (5) and 3.6490 (5) Å], resulting in a three-dimensional architecture.

In the title compound {systematic name: 2-[(3,5,6-tri­chloro­pyridin-2-yl)­oxy]acetic acid}, the herbicide triclopyr, C7H4Cl3NO3, the asymmetric unit comprises two independent mol­ecules in which the dihedral angles between the mean plane of the carb­oxy­lic acid group and the pyridyl ring plane are 79.3 (6) and 83.8 (5)°. In the crystal, pairs of inter­molecular O—H...O hydrogen bonds form dimers through an R22(8) ring motif and are extended into chains along [100] by weak π–π inter­actions [ring centroid separations = 3.799 (4) and 3.810 (4) Å]. In addition, short inter­molecular Cl...Cl contacts [3.458 (2) Å] connect the chains, yielding a two-dimensional architecture extending parallel to (020). The crystal studied was found to be non-merohedrally twinned with the minor component being 0.175 (4).

The title compound, C21H11ClF6N2O3 (systematic name: 1-{4-[2-chloro-4-(trifluoromethyl)phenoxy]-2-fluorophenyl}-3-(2,6-di­fluoro­benzo­yl)urea), is a benzoyl­urea pesticide. The dihedral angles between the central fluoro­benzene ring and the terminal di­fluoro­phenyl ring and chloro­phenyl ring system are 62.15 (5) and 88.03 (5)°, respectively. In the crystal, N—H...O hydrogen bonds link adjacent mol­ecules, forming R22(8) inversion dimers that pack into loop chains along the a-axis direction by short F...F contacts [2.729 (2) Å]. In addition, the chains are linked by weak C—H...π and π–π inter­actions [inter-centroid distances = 3.661 (2) and 3.535 (12) Å], resulting in a three-dimensional architecture.
