This study aimed to identify the effect of pea seed solarization obtained from the fields of the El-Wsita Region, Al-Jabal Al-Akhdar, Libya, and isolated species of Alternaria and Fusarium as well as Rhizoctonia, Botrytis, and Sclerotinia. The results of the research indicate that solar sterilization under the conditions of Shahat and Ras Lanuf for a period of five weeks reduced the rate of appearance of seed-borne fungi, with no differences between the two sites or between the types of plastic used, and all treatments were the highest effect against uncovered (control). The results didn’t show any decrease in the percentage of seed germination until after five weeks of covering. There was also a decrease in the length of the shoot in the seeds that are not covered with plastic under the conditions of the Shahat area, while those with the black plastic cover were less affected, while the decrease was significant for the seeds covered with transparent plastic under the conditions of Ras Lanuf. The transparent plastic coverage under the conditions of the two regions had a significant impact on the length of the root. This effect increased with time during the five weeks. The study concluded that pea seed solarization had a high potency against seed-borne fungi in the first few weeks without affecting their vitality.

There was also a decrease in the length of the feather in the seeds that are not covered with plastic under the conditions of the Shehat area, while the black plastic cover was less affected, while the decrease was moral for the seeds covered with transparent plastic under the conditions of ras Lanuf Transparent plastic coverage under the conditions of the two regions had a significant impact on the length of the leprosy, which increased the treatment time. The study concluded that pea seed sniffing had a high potency against seed-borne fungi in the first few weeks, without affecting their vitality.
