I'm looking for selective herbicides specifically designed to manage weed growth in watermelon crops. My focus is on products that effectively target common weed species without harming the watermelon plants. Ideally, I'd like to know about the application methods, recommended dosage, and any compatibility with other chemicals that might be used in conjunction. Additionally, please provide details about the formulation types available, whether they are liquid, granule, or another format. It's also essential to understand the expected timeframes for weed control effectiveness and any safety measures or restrictions to consider during application. If you have any product data sheets or technical specifications, please share those as well. Thank you!
