HOW TO CONTROL THE ONION 

 THRIPS 



The onion thrips is an insect so 

 small that it is almost invisible to the 

 unaided eye, but it is prolific, and the 

 most serious menace to the onion- 

 growing industry of this country. It 

 causes an annual loss to this crop 

 alone estimated by specialists of the 

 U. S. Department of Agriculture to 

 be at least $2,250,000. Though the in- 

 sect has a particular liking for onions, 

 it preys upon other garden and truck 

 crops, such as cabbage, cauliflower, 

 cucumbers and melons, and also has a 

 ravenous appetite for greenhouse and 

 many ornamental plants, particularly 

 roses. To aid growers in identifying 

 this insect and preventing the losses 

 for which it is responsible, Farmers' 

 Bulletin 1007, "Control of Onion 

 Thrips," has recently been published 

 by the U. S. Department of Agricul- 

 ture. 



The first indication that an onion 

 field has been attacked by thrips, says 

 the bulletin, is shown by the leaves, 

 which become whitened. In advanced 

 attacks the leaves are curled, crinkled 

 and twisted, and finally die down per- 

 manently. To control this pest, begin 

 spraying with nicotine sulphate solu- 

 tion as soon as there is any evidence 

 of the insect. If spraying is delayed 

 until hundreds of young thrips are 

 present the crop will be seriously in- 

 jured. The spray material is made by 

 the following formula: % pint of 

 nicotine sulphate (40 per cent.), 4 

 pounds of dissolved soap, and 50 gal- 

 lons of water. Spraying should be 

 done thoroughly and applied as a fine 

 mist. 



It is not advisable to plant other 

 crops, such as early cabbage and cauli- 

 flower, upon which the thrips feed, 

 near the onion fields. After onions, 

 cabbage and related crops are har- 

 vested, the field should be cleaned up 

 to destroy any breeding places of the 

 insect. They will continue to thrive 

 on any portion of these plants or 

 weeds that might remain in the field. 

 It is a good practice to plow as deeply 

 as possible and harrow the ground 

 after harvest. Much of the injury can

be avoided by planting as early as pos- 

 sible and by using quick-acting fertili- 

 zers after the onions are well set or 

 the bulbs have begun to form. Onion 

 fields should be watched constantly 

 and the plants should be kept growing 

 thriftily, since once the plants become 

 checked in their growth from any 

 cause the thrips will multiply more 

 rapidly than ever and it will be a hard 

 fight to save the crop.
