A method of protecting a crop by killing eggs of insects, or insects at the egg stage, the insects being detrimental to the crop, said method comprising applying to a locus where the eggs of insects are located or are expected to be located or are expected to be going to be located an effective amount of a compound of formula (I), or a salt thereof,

Method of combatting insect eggs and ovicidal compositions

A method has been found for protecting a crop by killing eggs of insects, or insects at the egg stage wherein the insects are detrimental to the crop. This method comprises applying to a locus where the eggs of insects are located or are expected to be located an effective amount of a compound of formula (I), or a salt thereof,

Method of combining insect eggs and ovicidal compositions

The invention describes novel 1-aryl-5-(substituted alkylideneimino)pyrazoles of formula (I) ##STR1## wherein typically preferred substituents are: R.sup.1 is cyano, nitro, or halogen;

Pesticidal 1-aryl-5-(substituted alkylideneimino)pyrazoles

Insecticidal compositions are provided which contain mixtures of certain benzoyl ureas and a synergist which is a methylenedioxyphenyl derivative. The invention also encompasses a method of controlling insects by subjecting them to an effective amount of the synergistic insecticidal compositions.

Synergistic insecticidal compositions

Novel phosphorous esters of cyanohydrins which exhibit outstanding pesticidal activity. A method of controlling pests by subjecting the pests to a pesticidally active amount of a compound of this invention is also covered.

Phosphorous esters of cyanohydrins

Insecticidal compositions are provided which contain mixtures of certain benzoyl ureas and pesticides. The invention also encompasses a method of controlling insects by subjecting them to an effective amount of the synergistic insecticidal compositions.

This invention relates to chewing insect toxicant compositions comprising (1) a 1-(mono-substituted phenyl)-3-benzoyl urea compound in admixture with (2) an amount sufficient to enhance the chewing insect toxicity of said urea compound of a phosphorous-containing compound. This invention is also directed to chewing insect toxicant compositions comprising an acceptable carrier and as the active toxicant an effective amount of the composition of this invention as well as to a method of controlling insects by subjecting them to an effective amount of the composition of this invention.
