Which U.S. wartime board put penicillin under an allocation system in July 1943?

The War Production Board placed penicillin under a wartime allocation system in July 1943.

The United States was producing penicillin on an expanding industrial scale, but supplies were still limited and military demand was enormous. On 16 July 1943, the War Production Board designated penicillin for controlled allocation, with supplies directed mainly to the armed forces and the U.S. Public Health Service.

This decision reflected penicillin’s status as a strategic wartime medicine rather than an ordinary commercial drug. Production in the United States rose dramatically, from about 800 million Oxford units in the first half of 1943 to 20 billion units in the second half. Military requirements consumed most output during 1944.

The War Production Board was a wartime economic agency responsible for coordinating industrial resources and manufacturing priorities. The Food and Drug Administration regulated medicines, while the Office of War Information handled public information and the War Manpower Commission dealt primarily with labor allocation; none was the board named in this question.
