Economic and simple citrus pest control law

Oranges use chemical agents to control pests and diseases, which are costly and susceptible to drug resistance. The author refers to the relevant information and has personally innovated and practiced to guide the fruit farmers to adopt the following simple and economical methods to control certain pests and diseases of citrus. The specific prevention and control methods are briefly described below.

1. Plant ash prevention and control leaf miners start when the shoots grow to about 3 cm at the tipping stage, until the new shoots are cooked, sprinkle once every 5-7 days, and continuously sprinkle 5-6 times, and at intervals. After the rain in the rain, the in-time make up. In the morning, when the dew is not dry, or after the rain, or after the water is sprayed, timely spray the plant ash on the leaf blade of the new shoots of citrus. During the whole shoot stage, the leaves should always adhere to the ash powder till the shoot leaves. After being matured. This method is suitable for greenhouses or open-air citrus nurseries, young orange gardens and potted ornamental oranges control citrus leaf miners.

2, lime water control ulcer disease with fresh kiln just out of the slaked lime powder 1 and 4 water converted to the filtrate after the lime mud filtrate, according to 5% dilution to control orange canker disease. Around 20 days before each shoot, shoots are applied every 10-15 days when the shoot reaches 5 cm in length and when the young fruit grows to 3 cm in diameter. After the fruit is collected, it shall be sprayed once during clearing of the garden. Each spraying shall be sprayed through the tree evenly, which can effectively prevent the occurrence of citrus canker and reduce the damage rate of leaves, fruits and branches. Spraying 5% lime water in the young fruit period can prevent sunburn and improve fruit quality.

3, water control Red spider use mechanical action so that water wash method can prevent orange spider mites. The method is to use a hose pumped by a pump or a spraying machine to reach the orchard. Use wire cutters or other clamps to make the nozzle hole-like (spray gun with direct spray gun head), so that when the water is flushed, there is a certain impact force to evenly wash the canopy. It can significantly reduce the population density of red and yellow spiders, and at the same time wash out the scale insects such as spines and aphids to reduce the incidence of soot; washing the dust on the leaves and fruits is beneficial to the photosynthesis of the leaves; Drought-resistance, cool weather, cool and prevent sunburn. However, the water spray must be performed before 10 o'clock in the summer. The precautions are that this method is not suitable for use during the flowering period, just for the new shoots and the fresh fruit setting period. It is suitable for use in the old ripening period of the shoots, and the fruit growth and expansion will be used from July to October. The water used must be clean, clean and free from contamination. Water source.

4. Gasoline kills the worms of the beetle and removes the worms in the hole of the burrow with a wire. Then the 70# or 90# gasoline is directly injected into the wormhole with a medical injector, and the wormhole is sealed tightly with the yellow mud. Plug, do not allow gasoline to evaporate to facilitate the killing of the worm. The injectable gasoline doses for the first instar larvae, the older larvae, and the mature larvae were 2 ml, 4 ml, and 6 ml, respectively. Because there are many holes in Tianniu, the hole closest to Tianniu should be injected with gasoline. After the injection of gasoline for prevention and control, there will still be insects excretion. This method is effective in preventing and curing Tian Long.

5. Smoke bone urine soaking solution prevents warts and aphids from cutting shredded tobacco bones (ie, leaves, stems, petioles and veins, etc. cannot be remnants of cigarette) 0.5 kg in 2.5 kg of human urine soaked for 8 days after filtration 25 kg sprayed on water can be used to prevent and control the occurrence of Citrus aurantium or aphid, such as adding 0.1% detergent or 0.4% urea in use, better control effect.

[Composition]

The main component of this preparation is human immunoglobulin, which is prepared by cold ethanol fractionation of human plasma from healthy donors. The manufacturing process contains a step to remove anticomplementary activity and a dual viral inactivation process. It contains a suitable amount of glucose or maltose as stabilizer (see table below), but does not contain any antiseptic or antibiotic. The distribution of IgG subclasses is close to the serum level of normal subjects and maintains the bioactivity of Fc fragment of IgG.

[Indications]

1. Primary agammaglobulinemia, such as X-linked hypogammaglobulinemia, common variant immunodeficiency diseases, immunoglobulin G subclass deficiency, etc.

2. Secondary immunoglobulin deficiency diseases, such as severe infection, septicemia of newborn, etc
