Question

Pusa A-4 variety is resistant to shoot and fruit borer.
A. False
B. True

Answer 1

Hint:
Leucinodes orbonalis, the brinjal fruit and shoot borer, is a moth species of the genus Leucinodes. The prior host plant is brinjal, where most of the economic effect of this species is noted. Secondary host plants include potatoes, tomatoes, turkey berries, etc.

Complete step by step answer:
Shoot and fruit borers lay eggs in the night on the lower surface of the green stems, young leaves, calyces of the fruits, and flower buds. After hatching, the caterpillar bores into the nearest flower, fruit, or tender shoot. Shortly after boring into fruits or shoots, they drill the opening hole with excreta. In young plants, caterpillars are reported to bore inside midribs of large leaves and petioles. So, the affected leaves may fall off. Larval feeding results in the withering of the young shoot.
Pusa A-4 is a variety of Okra cultivated as a result of hybridization and selection for insect and pest resistance. Okra variety of Pusa A-4 is resistant to Aphids, Jassids, root, and shoot borers. These plants have a longer shelf life, and the fruits of these plants have a lower volume of mucilage. Except during the cold season, it is ideal for growing throughout the year.

Option ‘B’ is correct

Note:
Symptoms of the shoot and fruit borer are wilting of terminal shoots/dead hearts, Boreholes on fruits and shoots plugged with excrement, flower buds shedding, and wilting and drying of leaves. We can manage this disease by removing the affected terminal shoot leading boreholes, removing the affected fruits, and destroying them, avoiding continuous cropping of the crop, and growing the varieties with narrow and long fruits in endemic regions.
