Okra is a warm-weather vegetable that is popularly grown in tropical and subtropical regions of the world. However, whitefly and jassid attack on okra can cause serious damage if not controlled in time. These pests feed on the sap of the plant, which weakens it, makes it vulnerable to diseases, stunts its growth, and reduces fruit yield. In this article, we will discuss the control of whitefly and jassid attack in okra.
Identification of the Pests:
Whitefly and jassid attack on okra could be easily identified. Whiteflies are tiny yellowish-white insects that are found on the undersides of leaves. They suck the sap of the plant, causing the leaves to wilt, yellow and eventually die. Jassids are tiny green-colored insects that are found on the upper surface of leaves. They feed on the sap by making holes in the leaves, which causes them to curl and turn brown.
Control Measures:
Let’s take a look at the various control measures that can be taken to prevent whitefly and jassid attack on okra.
1. Cultural Control: Okra plants should be kept healthy by maintaining adequate soil moisture and applying organic manures. Regular weeding and pruning of dead or infected leaves and branches should be done to reduce pest population buildup.
2. Mechanical Control: Whiteflies and jassids can be physically removed using vacuum cleaners or by shaking the plants and killing them using sticky traps.
3. Biological Control: Biological control involves introducing parasitic wasps, ladybugs, and lacewings, which feed on the pests and their eggs. Neem oil-based insecticides that use plant-extracts, or biological pesticides like Spinosad, can also be used.
4. Chemical Control: Pesticides like Malathion, Carbaryl or Acetamiprid, can be sprayed on the plants to kill the pests.
However, it is important to note that caution must be taken while using chemical control measures, as these can harm beneficial insects and pollinators.
Conclusion:
Whitefly and jassid attack can be controlled effectively with cultural, mechanical, biological and chemical control measures. Farmers must monitor their okra plants regularly and take prompt action if any signs of infestation are observed. By implementing and adhering to the control measures detailed in this article, farmers can prevent significant losses caused by these pests and ensure a healthy and productive crop of okra.
