Among the vegetable crops in the state of Gujarat, Bhinda is cultivated in large scale during monsoon and summer seasons. While the price of okra is good during the summer season, the area under okra cultivation has increased.Among the factors responsible for low production of oats is the loss of pests which is an important factor causing economic loss to the farmers. Insect pests such as sucking insects as well as stinging and fruit-eating caterpillars are found in the scales.

Crackle
Pukhya (Tadtadia) are cone-shaped pale green or yellowish in color and have a habit of walking diagonally. Both young and adult plants lose their juices by losing their trunks in the dry leaves, resulting in yellowing of the leaves and crouching upwards. If there is more nuisance, the cannon dries out.
White fly
The insect has white winged and yellow abdomen. While the chicks are flat, oval and scales-like. Both the young and the male remain on the underside of the leaf and suck the sap from the leaf resulting in yellowing spots on the leaf. If there is more infestation, the leaf turns yellow. The chicks secrete a viscous honey-like substance that covers the leaf surface and flowers so as to impede plant growth. In addition, these insects act as carriers of yellow vein disease.
Panakthiri
The adults of this insect are red in color while the cubs are orange in color. Cubs and adults damage the underside of the leaf by making a fine mesh of silk threads coming out of their body and sucking the sap from the leaf inside which causes white to yellowish patches on the leaf. If there is more infestation, all the leaves turn yellow and brown and eventually fall off.

Stinging and fruit-eating caterpillars
The caterpillars are white, black-headed and have black and brown spots on their bodies, hence the name "cabbage caterpillar". At the beginning of the crop, the caterpillars eat the tender stalks and buds of the oats so that the stalks wither and fall off. The caterpillar perches on the scales and eats the fetus, which is often found to be crooked and unfit for sale.
Integrated control system
Selection of varieties resistant to pests like Gujarat Bhinda-2, Parbhani Kranti.
Applying 5 gm Imidacloprid 20WS or 5 gm Thiomethoxam per kg of seed before sowing of Okra seeds controls the sucking pests like Taddadiya, Molo, Thrips, Whitefly and Panchatiri for up to one month.

The loss of Kabri caterpillar can be reduced by breaking the caterpillar stalks of caterpillars and burying them in the ground and weeding the caterpillars every second or third day.
In Okra crop, pheromone trap of Kabri caterpillar should be arranged at 40 or 50 per hectare and lure should be changed every 21 days.These pests can be effectively controlled by spraying herbal pesticides like Lemongrass Extract 3% or Lemon Oil 0.2% or Azadiractine based pesticide in 20 ml / 10 liters of water at intervals of 15 days.
For control of Kabri larvae, apply BTK powder twice per hectare at the rate of 1 kg, first spray at the onset of pest loss in okra fruit and second spray 15 days later.
Methyl-O-Dimetin 0.04% (10 ml / 10 liters of water) for effective control of sucking pests and stinging and fruit borer caterpillars in okra crop. Good control can be obtained by doing it at 20, 25 and 30 days after planting respectively.
If the infestation of cabbage caterpillar is more, spark 10 ml or indoxazacarb 12.5 sc. 10 ml Mix the drug in 10 liters of water and spray.
