58 INSECT PESTS OF FARM, GARDEN AND ORCHARD 



This may be applied broadcast, preferably late in the evening or 

 very early in the morning or it may be placed in small quantities 

 near the plants liable to attack. Chickens should be kept away 

 from the mash. 



Poisoned syrups are at times sprayed on plants so that the 

 adult insects, generally forms with sucking mouth parts, may be 

 killed before they lay their eggs. This method has been used to 

 some extent to control onion maggots by killing the flies which 

 produce them. 



6. Stickers or Adhesives 



It is sometimes necessary to use some material with the in- 

 secticide in order to make the spray stick to the leaves of plants 

 like cabbage. For this purpose a cheap form of syrup or molasses 

 is sometimes used. This is used also, at times, to make the spray 

 attractive to the insects so that they will eat larger quantities of 

 it and be more quickly killed. Syrup is not generally as good a 

 spreader or adhesive as some other materials. A soap containing 

 resin is as effective as any material in use. This material may be 

 made at home but the process is tedious and somewhat messy 

 and it will be more simple in most cases to purchase it. A simple 

 preparation of resin, used for the most part with bordeaux mixture, 

 is made by boiling 2 pounds resin, one pound sal soda and 1 gallon 

 of water together in an iron kettle for one to two hours. This 

 amount is needed for each fifty gallons of spray. 



Cactus solution, compounds of casein from milk and many 

 other substances have been used as adhesives and spreaders but 

 their use is not yet firmly established as successful.
