First, technical brief
The integrated pest control technology refers to the plant protection policy of “prevention first, comprehensive preventionâ€, in order to solve the problem of residual toxicity, resistance and re-infestation caused by long-term application of pesticides by rice aphids, and to minimize human and environmental pollution. Adhere to the prediction and forecast of pests and diseases, check the disease diagnosis, prescribe and control the drugs, and play the role of farmland ecological regulation. At the same time of high-quality, high-yield and high-efficiency agriculture, comprehensive use of ecological control, biological control, physical control, high-efficiency, low-toxicity, low-residue chemical pesticide control, etc., to form a system to coordinate control of rice aphids, not only to control the locust outbreaks The purpose is to enable harmful substances in products and the environment to meet the standards set by the state and produce high-quality products that are pollution-free and pollution-free.
Second, the operating procedures
1. Decrease the base of wintering locusts in the effective insect source field.
(1) Autumn and winter defense. In the autumn, seriously consider which are the effective insect source fields in Mingchun, using the dry heart group and the white ear group as markers to cut off the dead heart and white ear plants from the base before the larvae fall sufficiently into the wintering position; before the winter crops are planted, fine In addition to the rice piles in the soil preparation, the winter crops are grown in the early stage, combined with the cultivating and weeding, and the rice piles and manure are collected.
(2) Timely ploughing in the field: eradicating weeds in the field, timely irrigation and tilling, before the peak of the wintering generation of locusts, the paddy field is ploughed, thus eliminating the winter in the field, grass, rapeseed and grass The wintering locusts can greatly reduce the number of locusts in the year.
2, set up a trap to kill the field, rule the field pressure base. During the peak of the first and third generation moth moths in late April and July, the early rice, especially the early rice and early rice fields, the green seedlings have grown green, and the adult eggs can account for the total eggs. About 70% of the amount.
3, timely drying the field. The early rice is suitable for the sunbathing field before May 25 and the second night before August 25; the paddy field that is early enough for the seedling field to reach the early stage of the seedlings, and the paddy field that does not reach the seedling standard is sun-dried at the end of the sun-dried field; Footprints, feet not muddy or field splitting is appropriate. Sun field can effectively reduce the amount of eggs laid by the moth, and reduce the damage rate.
4. To control the prevention and control of anthill in the heading stage of late maturing varieties. The second and fourth generations of anthills often coincide with the early and late rice late maturity varieties at the heading stage (easy to invade), and the drugs are treated according to the maturity period of the rice and the hatching peak of the aphid eggs.螟Special medicines, such as 螟施净, 稻螟清, é”劲特, etc. to prevent and control the ants in the young ears, can reduce the rate of white spikes.
5, cultivation and treatment. Reasonable layout of rice cultivation, adjustment of the sowing period, promotion of the application of anti-aphid varieties, can relatively reduce the damage of aphids.
6, grab the fast ploughing. Early rice is harvested in time, harvested quickly, and harvested. For some dry and arid areas, the fields are pumped as early as possible, which can effectively eliminate most of the larvae and pupa in the grass, and greatly reduce the third generation of insect sources.
7, scientific medication. The selection of high-efficiency long-acting counterpart pesticides and guiding farmers to fight drugs according to the predicted time, mainly using sputum application, rice blast, triazophos, and ruthenium for locust control.
8. Protect natural enemies. In the rice fields, the "safety pool" and "safety forest" of some natural enemies are intentionally set up to create a place that is beneficial to natural enemies to inhabit and breed, so that natural enemies can avoid pesticide poisoning, thereby increasing the breeding coefficient of natural enemies and protecting the proliferation of natural enemies; At the same time, the natural enemy is used to reduce the killing of natural enemies and increase the rate of natural enemies.
9. Widely apply modern science and technology. Selecting genetically resistant varieties and promoting the application of advanced technologies and skills such as mathematical statistics information systems will have great effects on the comprehensive control of aphids.
