Agricultural poison

A tank has been built in and bags of agricultural poison have been emptied into it.

The man on top of the plane and those on the stairs are wearing a kind of protective mask against (clearly visible) dusting, but they are not very careful, the lower colleagues do not even bother to protect their breathing.

Under the torso is another type of atomizer, hidden behind the man on the floor, who hands the bags to the man on the stairs.

This photo is from January 1926 or later, because the aircraft then became the property of the "Luft Hansa" as can be seen on the hull.

In Germany, the Aero Lloyd under the direction of the biologist Max Wolff conducted spray tests for the first time on 22 May 1925 with a converted Fokker-Grulich in Biesenthal near Eberswalde. In the same year, regular agricultural flights started in Bavaria to combat harmful insects in trees (Kiefernspanner = pine spanner [Bupalus piniaria] and Nonne = nonvlinder) and until the end of the year 2950 hectares of forest were cultivated.
Junkers quickly showed leadership in this area with converted F 13 and W 33 aircraft.

Until 1928, 70 of these two types were used to spread pesticides against harmful insects, but the Fokker-Grulich also remained a frequently used aircraft.
