Risk of pesticide poisoning goes up when the product is highly toxic and when exposure happens over a longer period. A very toxic pesticide can cause harm with a small amount entering the body, so a brief contact or a short exposure can lead to poisoning if precautions aren’t followed. If exposure continues or repeats over days, weeks, or seasons, more of the chemical gets absorbed overall, and some pesticides can accumulate or cause lasting health effects, raising the risk of chronic poisoning. This is why safety practices are so important: follow the label, use the right PPE, keep exposure down, and observe re-entry intervals. Both higher inherent toxicity and longer exposure increase risk, so the statement is true.
