I diDn't read down the list too far but these read as though they are from old texts. The first one, on grasshopper control, calls for arsenic in it's control mixture, NOT A GOOD IDEA. Others include kerosene emulsion and tobacco extract, fumigation with hydrocyanic gas. BEWARE OF THESE TEXTS.

You do have to be very careful of pest (especially) and some disease control recommendations in old texts. Some are fine or almost innocuous (a number of the disease control sprays and dusts and organic pesticides of old are still organic gardener favorites) but the inorganic pesticides are terrible. Lead, arsenic, mercury. Fortunately it would not be easy now even to lay your hands on those old chemicals. Although I still (somewhere) have a bag of lead arsenate I found in the utility room of a house my parent's bought many years ago. I can store it safely enough but I don't quite know how to get red of it (I read of special hazardous waste disposal "days" every few years but each time too late.) One of America's top fruit horticulturists of the 1930s recommended using mercury (!) solution (corrosive sublimate, then available as capsules in any drug store) to kill troublesome earthworms in your yard (!!). Simply stunning when viewed from the perspective of today. Who would want to kill their earthworms anyway and who would use mercury in their yard?
