The compound has the CAS number <strong>91465-08-6<\/strong>, with the molecular formula C23H19ClF3NO3 and a molecular weight of 449.9 g\/mol.<\/p>\n<p>The term &quot;Cyhalothrin&quot; actually refers to a mixture of stereoisomers, but the <strong>lambda-cyhalothrin<\/strong> isomer (also known as \u03bb-cyhalothrin) is the most biologically active form and is widely used in commercial formulations.<\/p>\n<h2>What Are the Benefits?<\/h2>\n<h3>1. Rapid Knockdown Effect<\/h3>\n<p>One of the primary benefits of cyhalothrin is its <strong>fast-acting knockdown effect<\/strong>. Upon contact or ingestion, the insecticide quickly immobilizes insects, providing immediate control of existing pest populations.<\/p>\n<h3>2. Broad-Spectrum Activity<\/h3>\n<p>Lambda-cyhalothrin is effective against a wide range of insects, including beetles, caterpillars, aphids, thrips, mosquitoes, ticks, and flies.<\/p>\n<h3>3. Long-Lasting Residual Effect<\/h3>\n<p>Compared to natural pyrethrins, synthetic cyhalothrin provides <strong>prolonged insecticidal activity<\/strong>. This means fewer applications are needed to maintain effective pest control.<\/p>\n<h3>4. Low Mammalian Toxicity<\/h3>\n<p>When used according to label directions, cyhalothrin presents <strong>relatively low toxicity to mammals<\/strong> compared to organophosphate and carbamate insecticides.<\/p>\n<h2>What Are the Uses?<\/h2>\n<h3>Agricultural Applications<\/h3>\n<p>Lambda-cyhalothrin is extensively used in agriculture to protect crops including:<\/p>\n<ul>\n<li><strong>Cotton<\/strong>: Primary use for controlling boll weevils, aphids, and leafhoppers<\/li>\n<li><strong>Cereals<\/strong>: Wheat, barley, and rice protection<\/li>\n<li><strong>Vegetables<\/strong>: Tomatoes, peppers, cucumbers, and leafy greens<\/li>\n<li><strong>Frugt<\/strong>: Apples, pears, grapes, and citrus<\/li>\n<\/ul>\n<h3>Public Health Applications<\/h3>\n<p>Beyond agriculture, cyhalothrin plays a crucial role in <strong>public health pest control<\/strong>: mosquito control, tick and mite control, fly control, and cockroach elimination.<\/p>\n<h2>Sikkerhed og h\u00e5ndtering<\/h2>\n<p>When handling cyhalothrin, always use appropriate PPE including chemical-resistant gloves, protective eyewear, and long-sleeved clothing. The product is toxic to aquatic organisms and pollinators, so applications should be carefully timed.<\/p>\n<h2>Chemical Specifications<\/h2>\n<table>\n<thead>\n<tr>\n<th>Property<\/th>\n<th>V\u00e6rdi<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>CAS-nummer<\/td>\n<td>91465-08-6<\/td>\n<\/tr>\n<tr>\n<td>Molekyl\u00e6r formel<\/td>\n<td>C23H19ClF3NO3<\/td>\n<\/tr>\n<tr>\n<td>Molekylv\u00e6gt<\/td>\n<td>449.9 g\/mol<\/td>\n<\/tr>\n<tr>\n<td>Udseende<\/td>\n<td>Pale yellow to brown viscous liquid<\/td>\n<\/tr>\n<tr>\n<td>Renhed<\/td>\n<td>Typically 95%+ technical grade<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Frequently Asked Questions<\/h2>\n<h3>Q: What is the difference between cyhalothrin and lambda-cyhalothrin?<\/h3>\n<p>A: Cyhalothrin refers to the mixture of all isomers, while lambda-cyhalothrin is the most biologically active single isomer.<\/p>\n<h3>Q: How long does lambda-cyhalothrin remain effective?<\/h3>\n<p>A: The residual effect typically lasts 7-14 days, depending on environmental conditions.<\/p>\n<h3>Q: Is lambda-cyhalothrin harmful to beneficial insects?<\/h3>\n<p>A: Yes, lambda-cyhalothrin is toxic to beneficial insects including honeybees. Applications should be timed to minimize impact on pollinators.<\/p>\n<h2>Why Choose Our Cyhalothrin?<\/h2>\n<p>When sourcing Cyhalothrin for your agricultural or pest control needs, our products offer quality assurance, technical support, competitive pricing, and reliable supply.<\/p>\n<h2>Konklusion<\/h2>\n<p>Cyhalothrin (CAS 91465-08-6), particularly in its lambda form, represents a highly effective solution for modern pest management. Its rapid action, broad-spectrum activity, and relatively favorable safety profile make it a valuable tool for agricultural producers, pest control professionals, and public health officials alike.<\/p>","protected":false},"excerpt":{"rendered":"<p>What is Cyhalothrin?
