A supervised field trial was designed in Rajasthan Agricultural Research Institute, Durgapura, Jaipur, Rajasthan, to assess the dissipation and persistence of spiromesifen in chili fruits. Spiromesifen (22.9% suspension concentrate) was sprayed two times at an interval of 10 days at the recommended dose (96 g. a.i. ha−1) and double the recommended dose (192 g. a.i. ha−1) with four replications. Sampling was done according to the planned interval of days after the second spray. Extraction and cleanup were performed using the modified QuEChERS (quick, easy, cheap, effective, rugged, and safe) method and the spiromesifen residue was analyzed by GC–electron capture detector and confirmation performed using GC–MS. The average initial deposit of spiromesifen was 1.207 mg kg−1and 1.948 mg kg−1at the recommended and double the recommended dose, respectively. The half‐life values of spiromesifen ranged between 2.7 and 3.2 days at the recommended and double the recommended dose. The safe waiting period was calculated for the respective doses and it was concluded that an average of 7 days is safe for picking. The FSSAI (Food Safety and Standards Authority of India) have set the maximum residue limit of 0.1 mg kg−1 for spiromesifen in green chili. The theoretical maximum residue contribution value of spiromesifen was lower than the maximum permissible intake at both the applications on the 0th day. Hence, there will be no adverse effects on human health after consumption of green chilies.

The incidence of thrips was studied at Horticulture Farm, S.K.N. College of Agriculture, Jobner (Rajasthan) on garlic crop during Rabi season. The incidence of thrips on garlic crops was commenced in the first week of February and reached its peak in the second week of March. The predator, Coccinella septumpunctata Linn. was commenced in the second week of February and reached the maximum in the second week of March. The weather parameters viz., temperature, relative humidity, and sunshine (hrs) had a non-significant correlation with thrips incidence on garlic crop, whereas, predator, C. septumpunctata possess significant positive correlation.

The present study was conducted to find out the impact of teaching with intervention module on learning of the subject Environmental Science among slow learners, studying in the third class of Government Upper Primary Schools of Jaipur, Rajasthan. Out of total 53 slow learners identified from three schools of Jaipur, Rajasthan, slow learners of two schools were taught with intervention module in two different classroom settings: Remedial classes and Inclusive classrooms. The slow learners of the third school were taught with conventional methods by their subject teacher. The result showed significant improvement in the post-test score of slow learners in Environmental Science after being taught with an intervention module in both remedial classes and inclusive classroom settings. However, slow learners taught in inclusive classrooms scored higher in posttest as compared to those taught in remedial classes. No significant difference was found in the post-test score of normal students taught in remedial and inclusive classroom settings. Dealing with slow learners in the classroom is a universal matter of concern for all educators across the world so, the encouraging findings of this study can be an example for them. A simple change in the curriculum, pedagogy and classroom sitting arrangement that is pairing normal students with slow learners (peer tutoring) in regular classroom can bring a remarkable change in the achievement of not only slow learners but also of normal students. Besides this, there is a need for specific strategies and policies for making these students perform on par with normal students, such as allocation of more budget for training the workforce and establishing science and technology resource centers. The findings and limitations of the study suggest several possibilities for future empirical research in other subject at primary, secondary and higher level of education.
