ARSENATE OF LEAD 



Arsenate of Lead is an arsenical poison 

 for use against insects that chew and for 

 such insects as the fruit-flies that lap and 

 suck up sweetened liquids. It has also 

 been shown to have considerable fungi- 

 cidal value both when used alone or used 

 in combination with lime-sulphur. 



Arsenate of Lead is prepared in powdered 

 form. The powdered form can be used in 

 liquid sprays. The powdered form is also 

 used for dusting. 



The principal insects for which Arsen- 

 ate of Lead is used are: Apple-maggot, 

 brown-tail moth, bud-moth, cankerworm, codling moth, fruit- 

 tree leaf roller, gypsy moth, tent caterpillar, pear slug, 

 curculio, etc. 



Directions: 1 to 1% lbs., powder to 50 gallons of water. 

 Powdered Form.

ARSENITE OF ZINC 

 (POWDER) 



Arsenite of Zinc — This is a combination of arsenic with 

 zinc to form a quick acting, adhesive insecticide for use on 

 potatoes and some other truck crops. It is much more ad- 

 hesive and less caustic than Paris Green and kills quicker than 

 Arsenate of Lead. 



The great advantages of Arsenite of Zinc are: 



First— -It kills the buga so quickly they do not have a chance 

 to cause serious injury to vines. 



Second — It sticks to the vines so that it is not necessary to 

 respray aftjr every rain. 



Third — It can be used at sufficient strength to insure results 

 ■without burning or injuring the vines. 



Directions: 1 to lbs. powder to 50 gallons of water. 



First — Apply as soon as eggs begin to hitch. For spraying" 

 use at rate of two pounds to the acre — -this may require one 

 or two pounds or more of the powder to fifty gallons of water 

 depending upon the quantity of liquid distributed per acre by 

 the spraying outfit. The spray tank should be partly filled 

 with water and the powder sifted in slowly while the agitator 

 is running. 



Second — Make second application ten days to two weeks 

 later in order to cover new growth. 



Third — Make third application ten days to two weeks after 

 second.

BORDEAUX MIXTURE 



BORDEAUX MIXTURE is a combina- 

 tion of copper sulphate and lime. It is a 

 standard fungicide and may be used in 

 combination with insecticides. Its use is 

 indispensable in the control of black rot 

 of grapes and the blight of potatoes. It 

 is also used for apple-scab, bitter-rot, 

 cedar rust, leaf spot and downy mildew. 

 Directions: 6 to 7 pounds to 50 gallons of 

 water

ATOMIC SULPHUR 



This is pure sulphur treated by a spe- 

 cial process to convert it into a very 

 finely divided state in the form of paste, 

 so it can be readily diluted with water 

 and applied as a spray to coat fruit 

 and foliage with a thin film of sulphur 

 to prevent germination of fungous 

 spores. 



It is recommended for the control of 

 scab on peaches, brown rot on peaches, 

 plums and cherries and cedar rust on 

 apples. 



Directions: 5 to 7 lbs. to 50 gallons of water.

DRITOMIC SULPHUR 



The extended use of sulphur in the past decade has fully 

 established its fungicidal value and the advantages of its 

 use as a foliage spray to prevent russeting of fruit when 

 the temperature is above 70 degrees Fahrenheit. 



There has been a growing demand for fungicides in dry 

 form. To meet this demand, the General Chemical Com- 

 pany has developed a highly concentrated sulphur product; 

 a product that combines the advantages of Atomic Sulphur 

 with the advantages particular to dry powdered materials. 

 This new product will give the fruit the well-known sul- 

 phur finish, without interfering with the assimulatory func- 

 tions of the foliage or the development of the plant treated. 



DRITOMIC contains 90% available sulphur and 10% inert 

 matter. The inert matter, an adhesive and a spreader, is a 

 stable and non-injurious combination of ingredients which 

 do not yield readily to decomposition, even when spread in 

 a thin film on fruit and foliage. This eliminates any detri- 

 mental effect of changing chemical character. 



DRITOMIC permits the use of an arsenical with a small 

 amount of lime added, the same as with other fungicidal 

 sprays. The adhesive character of DRITOMIC prevents loss, 

 thereby adding to the value of the arsenical because of its 

 more permanent adhesion to fruit and foliage. 



The spreading character and free flowing nature of DRI- 

 TOMIC enables the covering of a larger area with less ma- 

 terial and permits the application to be made with a lower 

 pressure, thereby eliminating the chances of mechanical 

 injury and saving wear and tear on both pump and engine.

KAYSO is the combined casein 

 spreader and adhesive which 

 makes orchard and garden spraj r - 

 ing more economical and more ef- 

 ficient. Kayso is now used by 

 fruit and vegetable growers in 

 all parts of the United States. 



KAYSO should be added to all 

 sprays, both summer and winter. 

 Use it with all spray materials 

 and with any combination of ma- 

 terials. 



Ordinary spray collects in drops 

 on the smooth surfaces of buds 

 twigs, branches, leaves and fruit 

 Between the drops of spray art 

 numerous unprotected spaces 

 which permit infections by worms 

 and diseases. This deficiency of sprays is of great importance 

 when one considers that the hole made by the newly hatchec 

 Codling Moth worm or the Corculio on entering the frui 

 is about the size of a pin-head; the San Jose Scale, Psylla 

 Thrips, Red Spider, etc., and the eggs of all fruit pest! 

 are very small, and the spores or "seeds" from which Browi 

 Rot, Scab, Leaf Curl and all other diseases develop an 

 microscopic in size. Kayso enables you to get your tree; 

 completely covered by a protective film of poison, with ni 

 unprotected spaces.
