Spirotetramat has a good killing effect on small insects such as whiteflies, thrips, aphids, scale insects, pear psyllids, mealybugs, and blind bugs. It is currently the only insecticide with (bidirectional conduction) systemic and up-and-down conduction effects. After application, the agent can be absorbed and conducted to all parts of the plant through leaves and phloem, which can effectively protect new leaves and flowers and fruits. The insecticide method is mainly stomach poison and contact killing, and the lasting effect is long.
Spirotetramat has a unique bidirectional systemic conduction characteristic, and the dosage form is a suspension. Spirotetramat is effective for adults, larvae, nymphs, and eggs. It is first absorbed by the leaves, and then conducted to the roots, stems, leaves, and other parts of the plant. The agent is brought into the insect body by the pests to kill the pests. Even if the adults lay eggs after contacting the agent, the eggs cannot hatch normally.
Common spirotetramat preparations include single-dose and compound preparations. The compound preparation of abamectin and spirotetramat (4% Abamectin + 24% Spirotetramat) is recommended.
Abamectin·spirotetramat is absolutely effective in killing whiteflies, thrips, and aphids. The effect is significant and lasts for a long time. In the current economic crop areas, due to the serious use of drugs for many years and overdose, the resistance of thrips, whiteflies, and aphids has exploded. The common phenomenon is that growers cannot kill pests, so they continue to increase the dosage of drugs, which further stimulates the resistance of pests. In the absence of special drugs, abamectin·spirotetramat is a good choice.
However, some growers reported that the effect of using spirotetramat is not very obvious. Here we have to talk about the use method and skills of spirotetramat. We have introduced at the beginning of the article that spirotetramat's main insecticide method is stomach poison. Because it has a very good two-way systemic conduction effect, the absorption of the agent is the fundamental factor that determines the insecticide effect. For example, citrus has a thick wax layer on the leaves. It is difficult to retain the liquid medicine when it falls on the leaves, resulting in insufficient absorption of the agent and failure to achieve a good insecticide effect.
Drug application skills: In order to promote the absorption of the liquid medicine, the editor has demonstrated a very good combination experimentally. Before applying the medicine, we can first add 10-15 ml of vegetable oil adjuvant per 30-40 catties of water, and then add abamectin·spirotetramat. It should be mentioned here that the vegetable oil adjuvant should be added to the medicine barrel and stirred evenly before adding the agent. The agent must be diluted twice. The diluted agent should be added to the already stirred vegetable oil adjuvant barrel and stirred evenly again.
After completing the above steps, you can apply the medicine. After the first application of the medicine, the second application of the medicine should be carried out 5-7 days after the insect pests are seriously infested. The effective period can be up to about 30 days.
Special reminder: At present, some areas have developed different degrees of resistance to spirotetramat. It is recommended to choose compound pesticides or rotate with other types of insecticides to significantly slow down the occurrence of resistance. It is best to use spirotetramat before the outbreak of pests, which can effectively reduce the number of pests, reduce the damage to crops and economic losses caused by pests.
