Promote biotechnology to eliminate pests and diseases
Many pests have their own natural enemies, such as the ladybug, the ladybug, the ladybug, which are the natural enemies of the locusts; the grasshoppers and the six-pointed scorpion, which can control the damage of the hawthorn on the fruit trees; Natural enemies; daylight bees feed on apple aphid; Trichogramma can control apple leaf curlers, pear small heartworms, etc. In order to give full play to the role of natural enemies, the types of drugs should be strictly controlled during the period of natural enemies. At the same time, weeds and nectar plants (alfalfa, etc.) should be planted in the orchard line to attract natural enemies or artificial rearing to release natural enemies, increase the number of natural enemies and restore their self-control. Ability to apply biopesticide as much as possible. Biological pesticides include microbial pesticides, animal-derived pesticides and plant-derived pesticides. Bio-pesticide has no pollution and no residue after application. At present, the biological pesticides applied to fruit trees mainly include agricultural anti-120, polyoxomycin, green worm, Beauveria bassiana, Bt, pyrethrin, matrine, nicotine, and chlorpyrifos No. 3.
Using mineral-derived pesticides to control pests and diseases
Sulfur preparations and copper preparations in mineral-derived pesticides can be used in fruit tree production, and the main ones are stone sulfur mixture and Bordeaux mixture. Stone sulphur mixture has bactericidal, insecticidal and acaricidal effects, and is generally applied in the dormant period and early growth stage of fruit trees; Bordeaux mixture can prevent and cure a variety of diseases, and also has the effect of repelling and ovicidal activity on many pests, generally in the middle and late stages of fruit growth. Apply. However, peach trees are sensitive to stone sulfur mixture and some organic sulfur preparations, and are mostly applied in the dormant and flowering stages. For example, in the growing season, it is necessary to strictly control the application concentration and avoid the high temperature weather, otherwise it will easily cause the leaves to perforate and the fruit surface will be rough and shrink. In addition, peach trees are particularly sensitive to copper preparations, and young tissues are prone to phytotoxicity. Copper preparations such as Bordeaux mixture cannot be sprayed on peach trees.
