Abstract:
A process for protecting crops said process comprising applying to crops, the cultivated region in which they grow, before or after sowing, or their seed, which are in need of protection from birds, in an amount effective to repel birds, a compound having the formula: ##STR2## wherein: R.sub.1 is CN or methyl;R.sub.2 is S(O).sub.n R.sub.3 ;R.sub.3 is alkyl or haloalkyl;R.sub.4 is hydrogen, halogen, NR.sub.5 R.sub.6, S(O).sub.m R.sub.7, C(O)R.sub.7, C(O)O-R.sub.7, alkyl, haloalkyl, OR.sub.8 or --N.dbd.C(R.sub.9)(R.sub.10);each of R.sub.5 and R.sub.6 is, independently, hydrogen, alkyl, haloalkyl, C(O)alkyl, alkoxycarbonyl or S(O).sub.r CF.sub.3 ; or R.sub.5 and R.sub.6 together form a divalent alkylene radical which is interrupted by one or two divalent heteroatoms selected from the group consisting of oxygen and sulfur;R.sub.7 is alkyl or haloalkyl;R.sub.8 is alkyl, haloalkyl or hydrogen;R.sub.9 is alkyl or hydrogen;R.sub.10 is phenyl or heteroaryl which is unsubstituted or substituted by one or more halogen, OH, -O-alkyl, -S-alkyl, cyano or alkyl;X is a trivalent nitrogen atom or a C-R.sub.12 radical, the other three valencies of the carbon atom forming part of the aromatic ring;each of R.sub.11 and R.sub.12 is, independently, hydrogen or halogen;R.sub.13 is halogen, haloalkyl, haloalkoxy, S(O).sub.q CF.sub.3 or SF.sub.5 ; andeach of m, n, q, and r is, independently, an integer equal to 0, 1 or 2;provided that, when R.sub.1 is methyl, then R.sub.3 is haloalkyl, R.sub.4 is NH.sub.2, R.sub.11 is Cl, R.sub.13 is CF.sub.3 and X is N;wherein at least 72% of said crop, cultivated region or seed, which are in need of protection from birds, are effectively protected by the bird repelling action of said compound.
