at the College and they want us to tell them what problems trouble us. 

 If we do at any time the}' take it into consideration. 



Question : How much of the dust troubles you? 



Chairman: We are going to get away from that dust. I want to 

 keep to this subject. I will say right here, along that subject that I 

 would like this College to take up very serioush' this dusting proposition 

 before they tell anybody what to do. I tell you I won't tell them any- 

 thing to do right now. 



Mr. Halligari: We have been working since 1916 on the dusting 

 proposition and we have probably carried on dusting experiments on a 

 more extensive scale than any time in the past. For three years we have 

 carried on dusting tests here in the southwestern part of the State and in 

 the Grand Traverse section. We expect to continue the work in those 

 sections the coming year. As far as apples are concerned we have been 

 very successful concerning the scab. As far as cherries are concerned 

 we have been what a commercial grower would call successful with fungus 

 on the cherries but our experiments show that it has not controlled the 

 fungus as well as the liquid. On the dusting proposition with the apples 

 while they have been verj'- successful we are not confident at the present 

 time with our present program when it comes a wet season. For that 

 reason we have not recommended it and do not intend to recommend at 

 the present time the use of the dust as a substitute for the spray. We 

 will give you our results and will recommend it to growers who cannot cover 

 their trees with the spray at the proper time. Now in other States of 

 the Country they have not been as successful as we have been by the 

 use of the dust in controlling apple scab or pear scab and some other 

 diseases. Whether that is due to the fact that they are not efficient, do 

 not apply it at the right time, or because their climatic conditions are 

 different we are not able to tell. This dusting is a new proposition and 

 two seasons are not enough. We will simply give you the results of our 

 experiments as quick as they are available so you can apply them to your 

 condition as nearly as you can. I would say if a grower can get on a 

 liquid spray, put on the liquid spray because it is cheaper. We are 

 hoping that the dusting proposition will develop and that we will get 

 dust possibly finer and get better machinery so that in the near future 

 our dust, will be just as efficient as our liquid spray. We don't expect it to 

 be better than the spray. Better only if the man can do a more efficient 

 job in dusting than in spraying. At the present time the one advantage 

 is that you are able to get it on at the critical time. 



Member. I want to give my support to what Mr. Low has said in 

 regard to a spirit of cooperation between the practical fruit grower and 

 the Experiment Station at the College. Now think of the College in 

 two ways. We send our Children there to get a College education, 

 think of the Experimental Station as taking up these problems of growers. 

 It is the practical fruit grower that has the problems. It is the fellow 

 that is out in the orchard that gets these problems. We need some sort 

 of a Committee that can be appointed by this Association of practical 

 producers that can work in cooperation with Experiment Station and 

 keep a closer spirit of cooperation and keep this idea before both the 

 growers in the way of results and before the Experiment Station in the 

 way these things ought to be worked out. If it is in order I would like 

 to make this motion, that the Society appoint a Committee of fruit
