The Nevada County picayune., 1922-02-16

The government experts, E. k. COad and T. r. Cassidy, who for years have conducted extensive experiments at Tallulah, Louisiana, and at other points in the Mississippi Delta, give the following authentic information and advice on this subject:
 Many valuable lessons have been gained from the recent expansion of commercial weevil poisoning It has again been shown that the boil weevil can be poisoned with profit if condi- tions are favorable and if proper meth ods are used, but it has been empha- sized anew that unfayOrable conditions and improper methods can only lead to failure. A survey of the poisoning by farmers in 1920 shows that unfor tunately large proportions were not properly informed as to the conditions under which they should poison and the methods they should pursue. As a result, there were many unneces- sary failures If better results are to be secured in the future, the operation must be more thoroughly understood. The present circular is prepared to give in as brief and concise a form as possible, the information needed by a farmer in deciding, first. whether it will pay him to poison; and second, the methods he should follow.
 Wecvil poisoning is fully as import ant an operation as cultivation and deserves as much serious thought and attention. Unless you are willing to undertake it in this manner. you should not attempt to poison. Study these instructions carefully and follow them as closely as your conditions will permit.
 l Ii will pay to poison GD, if the Weevls are really injuring your crop seriously. and f2) if your land is suf- l ticiently fertile to yield at least one half bale per acre with weevil injury eliminated (3) if your farming or | @aniZation is such that you feel as sured that the right applications will be made at the right time and in the right manner; and (4) if you are will l ing to spend the full amount necessary to provide an adequate supply of dust ing machinery and poison.
 The general gains from weevil pois- oning under average conditions seem ] to be from 200 to 400 pounds of seed cotton per acre, but owing to varia tions in degree of weevi injury it is not safe to expect more than the lower | figure.
 Consequently, you should not poison | if the cost of the calcium arsenate, the cost of labor to apply it. and the depreciation on the dusting machines will total more per acre than the eur rent value of 100 pounds of seed cot ton. Hand guns should be figured as depreciating 100 per cent in season and the larger machines about 9 per cent
 In regard to machines: Make your acreage allotment according to the following schedule. and buy surplus, rather than a shortage of machines. as this will save you money.
 Hand guns: Do not allow over s acres to one hand gun. Do not attempt over 9 acres in one organization with hand guns. Do not supply individual tenants with hand guns and expect each to care for his crop successfully
 independent of the others Use hand guns only when no other machine is suitable
 One-mule Machine: This term is used to describe the new type of one mule machine which .is just being placed on the market. If sells at n medium price and is suitable for small farmers. This machine will cover from 15 to 20 acres in night of opcr- ation. If should be allotted only about 60 acres for season. This ma chine has only two nozzleS but will usually cover three rows at trip
 Cart Machines: This term is used to describe the two-wheel, twomule machine which straddles a TOW of cot ton It is the type most suitable for 1,,.,ro [, ,r,,,ore, FTlis ahiOa tx,flI faVpr from 25 to 90 acres in a night of oper-
