Summary. If the selected insecticidal product clearly lists the fruit tree as a registered object, its main active ingredient is relatively safe for the fruit tree and within the standard dose, and the fruit tree is not in the critical growth period or the safety interval of the product can be satisfied, then the use of the product may be more appropriate. But on the contrary, if the product does not include fruit trees or there is a large hazard, the dosage exceeds the standard or the safety interval is not satisfied, then it is best not to use it on fruit trees to avoid losses.
If the selected insecticidal product clearly lists the fruit tree as a registered object, its main active ingredient is relatively safe for the fruit tree and within the standard dosage range, and the fruit tree is not in the critical growth period or the safety interval of the product can be satisfied, then the use of the product may be more appropriate. However, on the contrary, if the product does not include fruit trees or there is a great harm, the dosage exceeds the standard or the safety interval is less than the lack of skin foot, then it is best not to use it on fruit trees to avoid losses.
Whether insecticidal sprays can be sprayed on fruit trees requires consideration of several paralytic aspects:1Objects and scope of registration of insecticidal products.
Many insecticide products are registered with a specified range of crops that can be applied, and if it is stated that fruit trees are not included, then it is generally not recommended to use them on fruit trees as this may cause some damage to the tree and fruit. 2.The active ingredient of insecticidal products and their effects on fruit trees.
If the main active ingredient of the product is a permissible and appropriate insecticide for fruit trees, it may be safe to use in standard doses. However, certain ingredients may increase the risk of more serious fruit tree disorders, depending on the specific product formulation.
3.The period between the development of the fruit tree and the safe interval between the brother of the product. Insecticide products usually cover different growth stages of different crops and give recommended safety intervals depending on the actual application.
If the fruit tree to be sprayed is in the critical growth period and the safety interval of the product cannot be met, then the use of the blind pants insecticide may cause some harm to the fruit tree and fruit, so it needs to be carefully considered. 4.The dosage and concentration of the pesticide used.
As long as the dosage and concentration are controlled within the recommended or allowable range of the product, it is generally safe. If the standard dose is exceeded, it is likely to pose a serious threat to the fruit tree, which needs to be strictly avoided.
Before use, it is recommended that you carefully read the instructions of the insecticidal products, and judge carefully according to the specific conditions of the fruit tree. If you still have doubts, you can refer to the correction to consult an agricultural technician. Hopefully, this information will be helpful to you.

It is best to spray fruit trees with insecticides at night.
Insecticides are a class of chemical agents that can repel sanitary pests, thereby preventing insect-borne diseases and protecting human health. When pesticides are used at night, the temperature and humidity can be lower, and various pests are also in a resting period, which will cause the pesticides to adhere for a longer period of time and can exert the best effect.
However, the timing of application of insecticides for fruit trees is not set in stone and should be considered in a variety of different contexts. Fruit farmers need to reasonably choose the best pesticide application time according to the comprehensive judgment of fruit tree varieties, climate, pest hazards, etc., in order to achieve the best control effect. At the same time, follow the pesticide publicity and use instructions, abide by the limit of pesticide application amount, ensure the market safety and personal safety of fruits, so as to contribute to the sustainable development of agriculture.
Introduction to insecticides
Insecticides are characterized by wide application and quick effect. Methods such as sprinkling eggplant cloth, spraying, fumigation, and attracting are often used to make the insecticide penetrate into the insect body to play a contact killing effect, enter the digestive tract of the insect body to play a stomach toxicity effect, and invasibly absorb and cultivate the insect body through the body surface stomata to play a fumigation effect; Or the insecticide is first absorbed by the domestic animal or plant, and when the insect bites the blood of the domestic animal or the juice of the plant's stems and leaves, the drug enters the insect body. Poisoning insects to death through these modes of action.
Pesticides should be safe for humans and animals, and less toxic. The insecticidal effectiveness is manifested in the ability to poison insects and the speed of knockdown. For different pests, precise application is required.
For example, for a variety of fruit tree herb-loving pests, we can determine the application time according to the time when the pest is cracked.
