The correct Answer is:
To determine the precautions Babanrao, an organic farmer, will take to control pests in his ladyfinger field, we need to analyze each statement provided: 1. **Use of ladybird and dragonflies to control butterfly caterpillars.** - This statement is incorrect. While ladybirds and dragonflies are beneficial insects, they do not specifically target butterfly caterpillars. In fact, they may affect other beneficial insects or crops, making this an unsuitable method for pest control in an organic farming context. 2. **Use of Nucleopolyhedrovirus to control arthropods.** - This statement is correct. Nucleopolyhedrovirus is a biopesticide that specifically targets and kills certain insect pests, particularly moths and butterflies. It is a safe and effective method for controlling pests in organic farming. 3. **Use of Bacillus thuringiensis to control butterfly caterpillars.** - This statement is also correct. Bacillus thuringiensis (Bt) is a bacterium that produces toxins harmful to certain insect larvae, including butterfly caterpillars. It is widely used in organic farming as a biological insecticide. 4. **Use of Trichoderma to control arthropods.** - This statement is incorrect. Trichoderma is a fungus that is primarily used to control fungal pathogens and is not effective against arthropods (insects). Therefore, it is not a suitable method for pest control in this context. ### Summary of Correct Statements: - The correct precautions Babanrao will take to control pests in his field are: - **II. Use of Nucleopolyhedrovirus to control arthropods.** - **III. Use of Bacillus thuringiensis to control butterfly caterpillars.** ### Final Answer: Babanrao should take precautions II and III to control pests in his ladyfinger field. ---
