At present, in the middle and late stages of strawberry production, facilities often encounter small pests such as aphids, whiteflies, thrips, and red spiders. These small pests are often too small to cause growers to pay enough attention. Once they are found to be infested The best time for prevention and control has already been missed, which will result in a serious decline in the quality of the strawberry product and a decrease in its yield. In order to ensure the quality and safety of agricultural products and avoid excessive pesticide residues in the fruit during late strawberry growth, the corresponding green prevention and control technology can effectively control the occurrence, development and spread of small pests and reduce the loss in production. Locust and whitefly control measures Laying silver ash film: The locusts are repellent to silver grey and can lay silver ash film on the strawberry crumbs. Suspension of yellow plates for trapping and killing: The use of insects for yellowing can trap and kill small pests such as aphids, whiteflies, and spotted lilies; a yellow plate is suspended at 15-20 cm above the strawberry plants, and a 2530 cm yellow plate is hung in each standard greenhouse. 30 pieces, which are periodically replaced as the case may be. Hummer control measures Hanging blue plate seduce: Use the thirst blue hung blue plate seduce, each standard hangs hangs 2530 cm blue plate 30 pieces, according to the situation regular replacement. Biological control: Lyceum bumble bee is the natural enemies of parasitic locusts and whitefly nymphs. Each adult larvae can parasitize and kill 100-120 locusts and whitefly nymphs; citrifolia isps are divided into 4-5 releases. , release once every 7-10 days, each release 2000-3000 wasps / acre. Red spider control measures Natural Enemy Prevention: At the initial stage of the damage of the red spider's center strain, special attention is paid to the import and export of the greenhouse and the area of ​​easy-to-familiar surroundings. Before the occurrence of red spiders, prophylactic release of 50-150 heads of mites or 3-6 heads per m2 of Chilean phytoseiids; after the occurrence of spider mites, at the initial stage of the damage of the center, prophylactic release of pasteurized Blunt locust 250-500 heads per square meter or Chilean mini tanned cockroaches 20 heads per square metre; serious sheds were created and biopesticides were used to depress the spider mites before release of the predator, using 200 times the mineral oil of 200 times 1% matrine azadirachtin or 1.8% avermectin for control, 5-10 days after application, according to the number of spider mites, control release or 1 to 5-1 ratio 10 Release the predatory cockroaches (Blattella uncinata, Chilean small-planted cockroaches); open the bottle cap and place it in the strawberry ridge; release it two weeks later and release it 2-3 times in a row. Precautions The larva is relatively small and has limited flying ability. Attention should be paid to uniform release and the bee-card should be evenly hung in the field. The larvae and predators are particularly sensitive to most chemical pesticides, and chemical insecticides are strictly prohibited after the release of natural enemies; temperature control At 15°C-30°C, humidity 70%-85%.
