The mechanism of spirotetramat inhibits fat biosynthesis in pests. It blocks normal energy metabolism, leading to death. When sprayed on crops, it gets absorbed through stems and leaves. It travels via phloem and xylem to all plant parts. Pests ingest it while feeding on plant sap, killing them. It also affects adult oviposition, preventing normal development. Spirotetramat is a novel keto acid derivative insecticide. It primarily acts as a stomach poison and secondarily as a contact insecticide. It controls various piercing-sucking pests like aphids, thrips, whiteflies, mealybugs, scale insects, and leafhoppers. It is particularly effective against larval stages of piercing-sucking pests.
Imidacloprid is a highly efficient neonicotinoid insecticide. It has broad-spectrum activity, high efficiency, low toxicity, and low residue. Pests are less likely to develop resistance. It is safe for humans, animals, plants, and beneficial insects. The insecticide works through contact, stomach poisoning, and systemic action. When pests contact the product, their central nervous system transmission is disrupted, leading to paralysis and death. It shows good efficacy within one day after application, with a residual period of about 25 days. The effectiveness increases with temperature; higher temperatures enhance insecticidal effects. It is mainly used to control pests with piercing-sucking mouthparts.
Features of Spirotetramat
1. Bidirectional systemic conduction ensures thorough pest control.
Bidirectional conduction means the solution moves up and down throughout the crop, reaching hard-to-access areas. Spirotetramat, a modern insecticide, conducts bidirectionally in xylem and phloem. The solution reaches plant leaves and bark, controlling hidden pests on lettuce, cabbage, and fruit tree bark.
2. Broad-spectrum insecticide.
Spirotetramat works on various crops, including citrus, grapes, cucumbers, peppers, eggplants, onions, watermelons, cotton, soybeans, and potatoes. It effectively controls pests like scale insects, spider mites, and aphids (such as apple aphids, citrus aphids, peach aphids, and root-knot aphids). It also targets leafhoppers and whiteflies, especially effective against concealed and shelled pests like scale insects and whiteflies.
3. Long-lasting efficacy.
A single application of spirotetramat can control generational pest outbreaks, providing effective protection for up to 8 weeks.
Features of Imidacloprid
1. Imidacloprid is an efficient, systemic, and broad-spectrum insecticide. It has stomach poisoning, contact killing, and antifeedant effects. It effectively controls pests resistant to organophosphates, carbamates, and pyrethroids. It works well against piercing-sucking pests like aphids, leafhoppers, planthoppers, thrips, and whiteflies.
2. It can easily cause resistance in pests. Due to its single action site, pests can develop resistance. Users should limit the number of applications, prohibiting consecutive use on the same crop. If field control effectiveness decreases, it's important to switch to organophosphate or other types of insecticides.
3. It has good fast-acting effects, showing significant efficacy one day after application, with a residual period lasting about 25 days. One application can protect some crops from pest damage throughout the entire growing season.
4. The effectiveness correlates positively with temperature; higher temperatures yield better insecticidal effects.
5. Imidacloprid is not only used for foliar spraying but is also suitable for root irrigation, soil treatment, and seed treatment. This is due to its stomach toxicity and contact action. While foliar spraying is effective and long-lasting, the residue on stems and leaves remains as the original imidacloprid structure. When treating soil or seeds with imidacloprid, the good systemic absorption allows the plant roots to take up the metabolite, which has higher insecticidal activity. This results in combined insecticidal action from both the original compound and its metabolites, providing superior control. Imidacloprid can also be mixed with fungicides when used for seed treatment.
Application of Spirotetramat
Prevention and Control of Aphids on Apples, Peaches, Fruit Tree Galls, and Pears
During the early occurrence of aphids, apply a suspension of 240 g/L Spirotetramat at a dilution of 8000 times with water, uniformly spraying on the branches and leaves. The control effect is over 95% 7 days after application.
Prevention and Control of Pear Psylla
At the initial occurrence of pear psylla nymphs, apply a suspension of 22.4% Spirotetramat at a dilution of 3000 to 5000 times with water, uniformly spraying on the branches and leaves. The control effect is over 96% 5 days after application and can reach 100% after 7 days.
Prevention and Control of Jujube Gall Midge
In the early stages of jujube gall midge larval occurrence, use a suspension of 240 g/L Spirotetramat at a dilution of 6000 times with water for uniform spraying. The control effect is over 92% 3 days after application.
Prevention and Control of Soft Scale Insects (e.g., Mulberry White Scale, Japanese Turtle Scale, Peach Scale)
During the early nymph stage, apply a suspension of 240 g/L Spirotetramat at a dilution of 2500 times with water, uniformly spraying on the branches and leaves. The control effect is over 96% 10 days after application.
Application of Imidacloprid
1. Application Range: Imidacloprid is suitable for vegetables, potatoes, cereal crops, corn, rice, sugar beets, cotton, citrus, and deciduous fruit trees.
2. Target Pests: Imidacloprid cannot be used to control nematodes and mites. It is primarily used to control piercing-sucking pests and their resistant strains, such as aphids, thrips, whiteflies, leafhoppers, planthoppers, and their resistant strains. It also shows good efficacy against some pests from the orders Coleoptera, Diptera, and Lepidoptera, such as leaf miners, leaf-mining moths, yellow-striped flea beetles, and pests from the genus Drosophila.
Due to its excellent systemic properties, Imidacloprid is particularly suitable for seed treatment and granular application. It can provide early and sustained pest control on cereal crops, corn, rice, potatoes, sugar beets, and cotton. For the aforementioned crops, as well as citrus, deciduous fruit trees, and vegetables, foliar spraying can control pests in the later growth stages. Foliar spraying is highly effective against black-tailed leafhoppers, planthoppers (such as brown planthoppers, gray planthoppers, and white-backed planthoppers), aphids (such as peach aphids and cotton aphids), and thrips (such as greenhouse thrips). It also provides control against whiteflies, rice stem borers, rice water weevils, and rice weevils, outperforming thiam ethoxam, emamectin benzoate, imidacloprid, and chlorantraniliprole. Additionally, it can be used as a sanitary insecticide and termiticide.
