Question: | "Are mercuric compounds all equally effective whether in suspension or in solution and do they all have the same corrosive action on spray pump valves?" |
Source of Question: | Virginia |
Answer/Response: | "We have been unable to detect any difference in the efficiency of mercuric compounds in the control of brown-patch whether they are applied in the form of dry powder or in suspension or solution provided in each case an even distribution is obtained. Red oxide of mercury and calomel are just as effective when applied with a spray pump if there is a device in the apparatus to keep the liquid thoroughly agitated. Most spray pumps are now equipped with satisfactory agitators. Some of the compounds of mercury have a corrosive action on spray pump valves, corrosive sublimate being by far the most damaging in this respect. Red oxide and calomel, however, are practically harmless to the valves of spray pumps." |
