Roman calendar date
The priest of Quirinus sacrificed a dog and a sheep in the grove of Robigo, praying that the rust disease would spare the young wheat.
aspera Robigo, parcas Cerialibus herbis
Scaly Rust, spare the blades of corn.
Background
For Roman farmers, one of the worst threats to the grain was robigo, the rust or mildew that turned the green stalks red and ruined the harvest. Rather than a vague evil, the Romans treated it as a power to be calmed, and late April, when the wheat was still young, was the time to do it.
Ovid says he met the ritual by chance. Returning to Rome from Nomentum, he found the road blocked by a crowd in white. The flamen of Quirinus was going to the grove of "ancient Robigo" to burn the entrails of a dog and a sheep, so Ovid joined them. He reports the priest's prayer: "Scaly Rust, spare the blades of corn", let the crops grow until the sickle, and turn your hands to hard iron and weapons instead of the tender wheat. Wind, rain and frost, the prayer says, do less harm than the rust when the sun heats the wet stalks.
Why a dog? The priest explained per Ovid that when the Dog Star rises, the earth is parched and the crops ripen too early, so a dog was placed on the altar for the star. By 354 the Calendar of Filocalus lists the same day as the SERAPIA, a festival of the Egyptian god Serapis.

Rome in AprilApril was full of agricultural festivals at a tense time: last year's grain…
Fields & crops
Spring sowing of millet and panic grass around the Ides; vines dug and vegetables planted out. Mildew on the young grain was the great fear per Columella 11.2; Ovid, Fasti 4.
Courts & law
Many days were taken up by games (Megalesia, Cerealia, Floralia), when courts did not sit; legal business squeezed into the gaps late Republic.
Senate & politics
Aediles who ran the April games used them to win votes; lavish shows could make a political career late Republic.
Military
Armies marched out to campaign; the sea lanes were open, so troops and grain ships moved again.
Festivals & religion
Veneralia (1 Apr.), Megalesia for the Great Mother (4–10 Apr.), Fordicidia (15 Apr.), Cerealia (12–19 Apr.), Parilia, Rome's birthday (21 Apr.), Vinalia (23 Apr.), Robigalia (25 Apr.) and the Floralia from 28 April per Ovid, Fasti 4.
Daily life
April was full of agricultural festivals at a tense time: last year's grain was running low and the new harvest was still weeks away. The Cerealia honoured Ceres, goddess of grain; the Robigalia (25 April) sacrificed a dog to keep mildew (robigo) off the crops per Ovid, Fasti 4.905–42. At the Parilia (21 April), Rome's birthday, shepherds purified flocks and leaped over bonfires per Ovid, Fasti 4.721–82.
Women of different ranks worshipped Venus and Fortuna Virilis on 1 April; Ovid says women of lower status bathed in the men's baths that day per Ovid, Fasti 4.133–50.
