Growth regulating insecticide methoxyfenozide
What is methoxyfenozide ?
The pesticide methoxyfenozide is a new type of specific phenylhydrazide low-toxicity insecticide. Cas 161050-58-4 has highly selective insecticidal activity against lepidopteran pests, with a mainly contact effect and a certain Systemic effect. This agent is a bionic ecdysone-type insect growth regulator. After the pests eat the agent, they will produce a molting reaction and start to shed their skin. Due to the incomplete molting, the larvae will die of dehydration, starvation and death. The mechanism of action of this agent is opposite to that of agents that inhibit molting of pests. It can be used to control pests throughout their larval stage.
The insecticide methoxyfenozide is a second-generation dihydrazide insect growth regulator. It has highly selective insecticidal activity against lepidopteran pests. It has no penetrating effect and phloem systemic activity. It works mainly through stomach poisoning. It also has certain contact and egg-killing activities.
The pesticide methoxyfenozide is a new type of specific phenylhydrazide insecticide with low toxicity. It is mainly used to control the larvae of lepidopteran pests, such as beet armyworm, cabbage armyworm, Spodoptera litura, cabbage armyworm, Cotton bollworm, golden streaked moth, American white moth, pine caterpillar, inchworm and rice borer, etc., suitable for crops such as cruciferous vegetables, solanaceous vegetables, melons, cotton, apples, peaches, rice, forest trees, etc. Its High efficiency and environmental friendliness meet the requirements and development trends of modern pesticides.
Methoxyfenozide Physical Properties
The insecticide methoxyfenozide is a white powder with a melting point of 202-205°C. The water solubility is <1mg/L at 20℃. Solubility in other solvents: dimethyl sulfoxide 11g/L, cyclohexanone 9.9g/L, acetone 9g/L. It is stable for storage at 25℃ and hydrolyzed at 25℃ and pH=5, 7 and 9.
Functional characteristics of methoxyfenozide
The insecticide methoxyfenozide is a type of insect growth regulator. It mainly interferes with the normal growth and development of insects, causing them to molt and die, and can inhibit feeding. This product is highly selective for water control targets and is only effective against Lepidoptera larvae.
The mechanism of action of methoxyfenozide
The insecticide methoxyfenfenozide is a derivative of tebufenozide. In its molecular structure, it has one more methoxy group on the benzene ring than tebufenozide. Its agricultural application performance is basically the same as that of tebufenozide, but there are two points. It is noteworthy that: first, the biological activity is higher than that of tebufenozide; second, it has better root systemic properties, especially in monocotyledonous crops such as rice. Methoxyfenozide is an ecdysone agonist, which causes lepidopteran larvae to stop feeding and accelerate the molting process, causing the insect to die due to premature molting before maturity. Methoxyfenozide has strong selectivity and is highly effective against lepidopteran pests. It can be used to control a wide range of lepidopteran pests on crops such as cereals, soybeans, cotton, grapes, citrus, vegetables, corn and ornamental plants, such as Noctuidae, Cabbage butterfly, armyworm, leaf roller moth and borer, etc. Methofenozide has no penetrating effect and phloem systemic activity, and mainly acts through gastric toxicity. It also has certain contact and ovicidal activities.
Regulation of insect ecdysone: The growth and development of insects is regulated by 20E, juvenile hormone, chitinase, etc. Insects regulate the growth and development period by changing the contents of various hormones in the body. In the larval stage, the content of juvenile hormone is high, and the content of ecdysone and chitinase is low. When the larvae molt, grow and develop, the insect prothoracic gland will secrete a large amount of ecdysone and stop the secretion of juvenile hormone, thus reducing the content of ecdysone. As the level of juvenile hormone increases, the content of juvenile hormone decreases, prompting the larvae to successfully complete molting and enter the next stage of growth. Ecdysone can interact with the ecdysone receptor EcR-superspiral protein USP to form a dimer (EcR-USP). The ecdysone receptor and superspiral protein are very important in completing the growth and development of insects such as molting, metamorphosis and reproduction. important role.
The role of the insecticide methoxyfenozide: methoxyfenozide competes with 20E for the ecdysone receptor EcR-USP binding site, thereby initiating molting, inducing the molting reaction to advance, and regulating insect growth to achieve insecticidal purposes.
The insecticide methoxyfenozide has strong selectivity and is highly effective against lepidopteran pests. It can be used to control a wide range of lepidopteran pests on crops such as cereals, soybeans, cotton, grapes, citrus, vegetables, corn and ornamental plants, such as nocturnal pests. Moths, cabbage butterfly, armyworm, leaf roller moth and borer, etc. Methoxyfenozide has no penetrating effect and phloem systemic activity. It is mainly gastrotoxic. It also has certain contact and ovicidal activities. Its disadvantage is poor quick effect, and its advantage is long lasting effect.

Methoxyfenozide prevents and manages insect resistance
①Delay the development of pesticide resistance in insects and extend the service life of pesticides
② Find appropriate ways to return insects that have developed resistance to pesticides to a sensitive state. The key to achieving insect resistance management goals is to reduce the selective pressure of pesticides on pests. The main problems currently encountered by methoxyfenozide in the market are the slowly growing resistance and poor quick-acting properties.
The best solution is to rotate and mix a variety of chemicals. Methoxyfenozide can be used with chlorpyrifos, phoxim, methomyl, deltamethrin, beta-cypermethrin, pyrofenitrile, and pyrochloride Urea, emamectin benzoate, flufluridon and fluflubenzuron are used in rotation or in compound form. Other studies have shown that the mixed use of methoxyfenozide and chlorantraniliprole has a synergistic effect on Spodoptera exigua. Therefore, chlorantraniliprole can be used to control Spodoptera exigua that is resistant to methoxyfenozide. moth.
