Spirotetramat is a next-generation systemic insecticide with a unique two-way transportation ability and innovative lipid biosynthesis inhibition mechanism.
Its excellent performance against aphids, whiteflies, mealybugs, scale insects, and other sucking pests makes it an important solution for modern agricultural pest management.
With proper application methods and resistance management strategies, Spirotetramat can provide reliable, efficient, and sustainable protection for various crops worldwide.
What is spirotetramat insecticide?
Spirotetramat is a modern systemic insecticide belonging to the tetronic acid derivative chemical family. It is widely recognized for its unique two-way systemic movement in plants and excellent control performance against various sucking pests.
Unlike traditional contact insecticides that mainly act on pests exposed on plant surfaces, Spirotetramat can be absorbed by plants and transported through both xylem and phloem systems, allowing active ingredients to reach newly growing tissues and hidden pest populations.
Due to its innovative mode of action, long-lasting protection, and effectiveness against resistant pest populations, Spirotetramat has become an important tool in integrated pest management programs for vegetables, fruits, cotton, and other high-value crops.
Spirotetramat Mode of Action
Spirotetramat works by inhibiting acetyl-CoA carboxylase (ACC), an essential enzyme involved in fatty acid biosynthesis in insects. According to the Insecticide Resistance Action Committee (IRAC), Spirotetramat belongs to Group 23 insecticides, classified as lipid biosynthesis inhibitors.
After application on plant leaves, Spirotetramat penetrates plant tissues and is converted into its active metabolite, Spirotetramat-enol. This active form interferes with lipid production in insects, affecting their growth, development, reproduction, and survival.
Because lipid synthesis is essential for insect development, Spirotetramat mainly affects immature stages such as larvae and nymphs. It also reduces the reproductive ability of adult insects, helping to suppress pest population growth over time.
Advantages of Spirotetramat
One of the most important advantages of Spirotetramat is its unique ambimobile systemic property.
After foliar application, Spirotetramat metabolites can move in two directions:
- Upward movement through xylem
- Downward movement through phloem
This bidirectional transportation allows the active ingredient to distribute throughout the plant, including:
- New leaves
- Growing shoots
- Roots
- Hidden feeding areas
Compared with traditional insecticides that only protect treated surfaces, Spirotetramat provides more comprehensive internal protection and can effectively control pests feeding on different parts of plants.
Main Target Pests Controlled by Spirotetramat
Spirotetramat is mainly used for controlling piercing-sucking insect pests that damage crops by extracting plant sap.
Aphids
Spirotetramat shows excellent activity against many aphid species. It can reduce aphid populations by affecting insect development and reproduction, making it suitable for long-term aphid management.
Whiteflies
Whiteflies are major greenhouse pests worldwide. Due to its systemic movement, Spirotetramat can reach feeding sites that are difficult for conventional contact insecticides to cover.
Scale Insects and Mealybugs
Spirotetramat is particularly valuable against scale insects and mealybugs because these pests often hide in protected locations on plants where direct spray coverage is difficult.
Psyllids and Other Sucking Pests
Spirotetramat also provides effective control of psyllids and other sap-feeding insects in various agricultural production systems.
Application Crops of Spirotetramat
Spirotetramat can be widely applied in many agricultural crops, including:
Fruit Crops
- Citrus
- Grapes
- Apples
- Pears
Vegetable Crops
- Tomato
- Pepper
- Cucumber
- Leafy vegetables
Field Crops
- Cotton
- Soybean
- Other commercial crops
Its systemic characteristics make it especially suitable for crops where continuous protection of new plant growth is required.
