Applicable crops and application methods of diflubenzuron

Diflubenzuron is a specific and low-toxicity insecticide that belongs to the benzoylurea class. It exhibits both stomach poison and contact killing effects on pests. By inhibiting chitin synthesis in insects, it prevents the formation of a new exoskeleton during molting, leading to the deformity and death of larvae. However, its efficacy is gradual. This pesticide is particularly effective against lepidopteran pests. It is safe to use, with no adverse effects on fish, bees, or natural enemies (predators and parasitoids).

Diflubenzuron Applicable crops

Diflubenzuron has a wide range of applications and can be used extensively on various plants including apple, pear, peach, and citrus fruits, as well as crops such as corn, wheat, rice, cotton, and peanuts. It is also suitable for cruciferous vegetables, solanaceous vegetables, melons, tea trees, and forests. Diflubenzuron is primarily used to control lepidopteran pests, such as cabbage worms, diamondback moths, beet armyworms, fall armyworms, corn earworms, oriental fruit moths, citrus leaf miners, whiteflies, tea leaf rollers, bollworms, gypsy moths, pine processionary caterpillars, leafrollers, and leaf miners, among others.

Diflubenzuron method of use

The main formulations of Diflubenzuron are as follows: 20% suspension concentrate (SC), 5% and 25% wettable powder (WP), 75% wettable powder (WP), and 5% emulsifiable concentrate (EC).

  1. The 20% suspension concentrate is suitable for conventional spraying and low-volume spraying. It can also be applied using aerial spraying. When using this formulation, the liquid should be shaken well and then diluted with water to the desired concentration, forming a milky suspension for application.
  2. For the control of pests in forests, such as pine processionary caterpillars, gypsy moths, leafrollers, and tussock moths, the recommended dosage is 7.5-10 grams per mu (approximately 666-888 grams per hectare) with a dilution ratio of 4000-6000 times.
  3. For agricultural crops, such as diamondback moths, peach twig borers, and oriental fruit moths, the recommended dosage is 5-10 grams per mu (approximately 444-888 grams per hectare) with a dilution ratio of 5000-8000 times.
  4. For fruit trees, including whiteflies, bollworms, cabbage worms, leaf rollers, armyworms, and tent caterpillars, the recommended dosage is 5-12.5 grams per mu (approximately 444-1110 grams per hectare) with a dilution ratio of 3000-6000 times.

Important note: Avoid contact between the pesticide solution and alkaline substances to prevent decomposition. Diflubenzuron is a growth regulator and should not be applied during the high or mature stages of the target pests. It is most effective when applied during the early stages of pest development.

Please note that the measurements provided are based on Chinese units of area (1 mu is approximately 0.0667 hectares or 667 square meters).
