CITRUS CROP ESTIMATE. 



The following estimate for the citrus crop has been received from 

 G. Harold Powell, manager of the California Fruit Growers' Exchange, 

 under date of November 4, 1913 : 



The estimates or oranges and lemons made by the Exchange shippers 

 at all of the different shipping points indicate a crop for the State of 

 38,000 to 40,000 carloads. This estimate would, of course, be changed 

 one way or the other, depending upon climatic conditions from now on. 

 The indications are, however, that there will be about 33,000 or 35,000 

 cars of oranges and approximately 4,500 cars of lemons. Of the 

 oranges, these preliminary estimates show about 8,000 cars of Valencias 

 and 23.000 to 25,000 cars of Navels. There are usually from 1,500 to 

 2,000 cars of other varieties of oranges. Of course these estimates are 

 preliminary, but they are based on accurate individual estimates of the 

 growers in the different sections. 



SPRAYING TO CONTROL TOMATO THRIPS. 



In the report of the Florida Agricultural Experiment Station for 

 1912. issued March, 1913, pp. 61-62, R. T. AVatson has published some 

 interesting things regarding spraying for the tomato or grain thrips, 

 Enthrips tritici Fitch. He found that the majority of the tomato blos- 

 soms, instead of setting fruit, turned yellow, and if touched dropped 

 off at the node. When these were opened they were found to contain 

 six or more thrips apiece. The pistils and stigmas were attacked. Eggs 

 were found in the style and pedicle, and there was no doubt but that 

 the dropping was caused by the thrips. A trial piece was treated with 

 a spray composed of: 



Commercial lime-sulphur (33° Baume) .")i gallons 



Black-leaf "40" 14 fluid ouuces 



Water 200 sallons 



• Seventy-eight per cent of the thrips were killed. — E. 0. Essig.
