RECOMMENDATIONS. 



In \ jew of the success attained in icducin^r injuiy to fiuit and 

 foliaire by the orange thrips, it is believ(;d tiiat it \\ ill l)e j)os-ihle to 

 control this species in normal seasons with four a]>plication- of TniK!- 

 sulphui" combined with bhu-kleaf tobacco extract. 



JI.Mi; OI AI'I'I.KAIIOX. 



Three of the t I'cat nient - -hould be made in the -jd'ing to fn-e \\i<> 

 fruit and -pi'inii' irrowih- of foliaire fi-om injui'V. -incc the nutre 

 -evere marking of fruit is done while the fruit i- small. 'I'he fourth 

 treatment should be made in August or September, according tr; sea- 

 son, for the protection of the later irrowth- of foliage, and should be 

 time(l to catch the thrips when numerous, but b<'foi-e the leaves show 

 much curling. The three spring aj^plications .-honld be mad(! ai>out 

 as follows: 



First. Just after most of tlie f)Otnls have fallen from tin- l)Iossoms. 



Second. Ten to fourteen (i;iys Jifter tlu- lirst. 



Third. From throe to four weeks from the time of the s<'<ond treatment. 



The dates for spraying in any gi\en season nni-t be timerl by the 

 abundance of thrips.

Lime-sulphur -olutions should be diluted according to den-ity. 

 In the homemade product this may be determined by the tise of a 

 liaiune or a specific gravity 'Spindle. 'I'he densitv of the commercial 

 jjroduct will be ftated by the manufacturer or may be obtained by 

 the use of the spindle, 



Lime-sidphur solution of a density of '■'>-'/' liaume should Ix- diluted 

 at the rate of 1 volmne to 7~t volumes of watei-: that of a density of 

 '',(','' Baume should be dilutee] ;it the rate of 1 vf.bnne to 80 volumes 

 of water. Therefore the formida f')r oran^i-e-thrips spraying
