3IO MISSOURI AGRICULTURAL REPORT. 



they may collect upon the first few rows of corn, where they can be readily 

 killed by means of kerosene emulsion spray. 



It is a fact that chinch bugs die like magic before a spray of kero- 

 sene emulsion or five per cent kerosene mechanically mixed with water; 

 and if we could always be sure that in this migration from the wheat 

 to the corn field, the chinch bugs would collect in immense numbers 

 upon the first few rows of corn and stay there long enough to allow of 

 spraying them, this would be the ideal method of exterminating them 

 from the corn field, or of preventing them from entering the corn. 



An agriculturist should watch the chinch bugs, and when he finds 

 them collected on the first few rows of corn or in masses along his bar- 

 rier, he should be thankful, because he now has his bugs in the very 

 best condition possible for obtaining his revenge. When the bugs col- 

 lect in such places the agriculturist should drop every other work and 

 spray these insects at once, especially if they are upon the fist few 

 rows of corn, since they will soon spread through the corn ; and when 

 this happens, he is barred from any further method of killing them. 



I would advise the agriculturist to purchase one of the new pumps 

 with the kerosene attachment. These pumps are made by the better 

 manufacturers, and cost very little more than the pumps without such 

 attachments. They save an immense amount of time and labor, especially 

 for such purposes as chinch bug extermination. The pumps do away 

 with the necessity of making kerosene emulsion. All that is needed is 

 to turn pure kerosene or coal oil in the receptacle attached to the pump 

 for that purpose, and set the indicator at five per cent ; put the pump 

 in a barrel of water and spray without any further trouble. This five 

 per cent mixture of kerosene kills the bugs readily, and does not injure 

 the plants. 



In spraying for chinch bugs it is necessary to touch every bug -n 

 order to kill it, because these bugs are killed by contact with the kerosene. 

 This necessitates thorough work, and one must, therefore, spray on all 

 sides of the plant that is infested with these bugs, but where the bugs 

 have collected in this way in immense numbers, the agriculturist will 

 be delighted to do the work and see the bugs die so rapidly and in such 

 great numbers. 



Where one has no modern spray pump with the kerosene attach- 

 ment, then an ordinary spray pump may be used ; but one nnist make 

 kerosene emulsion. This is made in the following way: Dissolve one- 

 half pound of hard soap (in case you wish to use soft soap one pound 

 should be taken) in one gallon of boiling soft water; after the soap has 

 been thoroughly dissolved and stirred through the water, remove this
