Background: Pesticide poisoning is a burning occupational health issue across the world. The pesticide use in the cardamom plantations of Idukki district, Kerala, India is one of the world's highest. However, limited studies addressed its ill effects on the health of pesticide applicators.
Aims: To assess the magnitude of acute pesticide poisoning (APP) among pesticide applicators and understand the nature of severity based on their occupational characteristics.
Settings And Design: A descriptive cross-sectional study was conducted in 2018. A total of 300 pesticide applicators with minimum 1-year experience (79.3% males) were selected from 30 randomly selected cardamom plantations in Udumbanchola Taluk.
Methods: WHO Field Surveys of Exposure to Pesticides Standard Protocol and Murphy's method of Farmer Self-Surveillance system of pesticide poisoning were used for assessing pesticide exposure and APP, respectively. Statistical analysis used: Descriptive (frequencies) and exploratory statistical analyses (Pearson's Chi-square test) were done using IBM SPSS 23.0.
Results: The prevalence of APP in this study was 100% as all the pesticide applicators reported at least one sign and/or symptom of APP. The mild APP was more prevalent (80.7%), followed by moderate (18.7) and severe (0.60). Decrease in duration and frequency of spraying, use of motor pump sprayer, safe storage and disposal of pesticides, and proper personal hygiene were found to reduce the severity of APP.
Conclusion: All the pesticide applicators in cardamom plantations of Idukki are at risk of APP. It is important to train them about the measures to prevent the same.

Rice blast caused by is one of the most economically important rice diseases. Fungicides such as isoprothiolane (IPT) have been used extensively for rice blast control, but resistance to IPT in is an emerging threat. In this study, molecular mechanisms of resistance in IPT-resistant mutants were identified.

A toxicokinetic model of the pyrethroid insecticide lambda-cyhalothrin (LCT) was developed to relate absorbed doses to urinary cis-3-(2-chloro-3,3,3-trifluoroprop-1-en-1-yl)-2,2-dimethylcyclopropanecarboxylic acid (CFMP) metabolite levels used as a biomarker of exposure. The model then served to reconstruct absorbed doses in agricultural workers and their probability of exceeding the EFSA Acceptable occupational Exposure Level (AOEL). The toxicokinetic model was able to reproduce the temporal profiles of CFMP in the urine of operators spraying pesticides using the optimized model parameters (adjusted to human volunteer data).

Unmanned aerial vehicle (UAV) pesticide application in recent years owing to its importance such as time saving, reduction in human drudgery and also reduction in pesticides application rate. UAV has a great potential to address the problem involved in manual chemicals spraying in tall crops like coconut plantation where at present operation performed by manual climbing involves lots of drudgery and life risk. The current study aimed to understand the most influencing spraying parameters, such as spray height and spray time of the UAV sprayer on droplet characteristics such as spray droplet size, spray coverage and spray deposition at different layers (spindle, middle and bottom) of coconut tree canopy.

Prostate cancer is a common cancer among males in the US, but little is known about its risk factors, including trace elements. The primary aim of this study was to examine prostate cancer and its association with arsenic and selenium in toenails. We conducted a small, nested case-control study of men residing in Iowa within the Agricultural Health Study cohort, where we also collected toenail samples to test for arsenic and other trace elements.
