(2) Popularizing pesticides with high efficiency, low toxicity and low residue; Strengthen field management and adopt biological (natural enemies of crops) and physical (insect net) measures for prevention and control; For the phytotoxicity caused by spraying, spraying water can be used for leaching. Strengthen publicity, supervision and management (strengthen the investigation and management of illegal pesticides; Strengthen the propaganda of scientific and rational use of pesticides and improve farmers' awareness of environmental protection; Carry out comprehensive and systematic detection of pesticide residues). (Answer 3 points, 6 points).

Test analysis:

Question (1), through the "schematic diagram of pesticide pollution to the environment", we can know that the process of pesticide pollution to human body is mainly reflected in the pollution of pesticides to the air, water, soil and biology. And through food chain enrichment, pesticide residues in food are ingested into human body, which is harmful to human health.

Question (2), the main measures to control pesticide pollution can be analyzed from the following aspects: comprehensively control diseases, pests and weeds, reduce the use of chemical pesticides, and promote pesticides with high efficiency, low toxicity and low residue; Strengthen field management and adopt biological and physical measures for prevention and control; Measures to strengthen pesticide management, further improve pesticide management institutions, establish and improve pesticide analysis and monitoring system, and strengthen the training of rural plant protection personnel.

Comments: This question is moderately difficult. The key to solve this problem is to pay attention to obtaining information from relevant diagrams and examine students' language organization ability. The main measures to prevent and control pesticide pollution should be answered in combination with the actual situation, which can turn difficult into easy, but students should pay attention to honing their own language in their usual study.
