The farmer crushed the leaves of arani and kept the juice for overnight. The next day the farmer coated the jowar seeds with this juice before sowing. Approximately 1.5 kg of arani leaves are needed for 20 kg of jowar seeds. Crush the leaves of Arni or Arani (Clerodendron multiflorum) and keep the juice overnight. The next day coat the jowar seeds with this juice before sowing.

Formulation: Crush the leaves of Arni or Arani (Clerodendron multiflorum)
Ingredients: The leaves of Arni or Arani (Clerodendron multiflorum)
"The rice weevil, Sitophilusoryzae L. (
Coleoptera: Curculionidae), is one of the major stored-grain pests of cereals throughout world. During the present study an attempt was made to evaluate the insecticidal and repellent activities of crude methanol extract of Clerodendrumserratum L. against the rice weevil, Sitophilusoryzae L. Insecticidal activity was evaluated using a no-choice test with treated filter paper with wheat grains while repellency evaluated using a choice test with treated filter paper. The crude methanol extract was found to possess moderate insecticidal efficacy against S. oryzae with maximum mortality of 63% at 32 mg/mL (w/v) 7 days after exposure however toxicity depended on both concentration and duration of exposure. The methanol extract was highly repellent against S. oryzae ranging from 23 and 77% at 30 minutes to 2 h after exposure and from 47 to 97% at 4 to 24 h after exposure. The exposure period appeared to be the most important factor affecting the repellency activity of crude extract of C. serratum. Therefore, these leaves extracts may be suggested as admixtures in the integrated management of S. oryzae infestation of cereals during storagw. [Jadhav, Adhikrao&Yankanchi, Shivanand& .P.M, Patil. (2014). Insecticidal and repellent activities of Clerodendrumserratum L. leaf extract against rice weevil, Sitophilusoryzae L. Asian journal of biological and life sciences. 3. 35-39.]"
"Efficacy of certain Clerodendrum leaf crude extracts were evaluated in the laboratory against third instar larvae of Spodopteralitura and Helicoverpaarmigera. Toxicity was assessed through topical application method. The extracts of C. inerme, C. viscosum and C. philippinum were found to be more effective to both the insects. Antifeedant assay was conducted through leaf disc choice tests. Crude extracts of C. inerme, C. viscosum C. Phillipinum C. splendens, and C. multiflorum exhibited strong antifeedant activity (> 50%) at a dosage of 100-mg/ 21cm2 to S. litura. However, the H. armigera showed less antifeedant activity with more feeding of extract treated leaf in all doses. The extracts of C. inerme, C. viscosum and C. Phillipinum were exhibiting both activities. Larval growth inhibition activity was evaluated through diet. C. philippinum extract was revealed strong growth inhibition to S. litura. Extract of C. serratum showed maximum (75%) growth inhibition in H. armigera. The other plants which were tested showed moderate effects towards these pests. Based on their efficacy, some of these plant extracts have potential for use as alternative crop protectants against lepidopteran pests."
