Farmers know that if you reduce harmful insects and diseases in your crops, you have a chance for a better harvest. Today, many farmers and experts praise Integrated Pest Management, or IPM. IPM is a series of choices and methods to control insects, diseases and fungi. The program provides current information on how pests live and act in the environment.
A number of non-governmental and other organizations in many countries provide education in IPM. Farmers can get information meant for the needs of their own land. They can learn to recognize possible problems and how to plan crops to help prevent failures.
Paul Jepson heads the Integrated Plant Protection Center at Oregon State University. He says farmers who have attended field schools in Asia and Africa have increased the use of IPM. And he says this has cut pesticide use.
James Frederick is an IPM expert with Clemson University's Pee Dee Research and
Educational Center in South Carolina. He says one basic IPM method is to plant as early in the season as possible so that most of the crop will be in by the time a disease or pest arrives.
Not all insects are pests. Some are helpful. IPM programs help farmers learn to identify different kinds.
Another IPM method is rotating crops. Farmers do not plant the same crop season after season in the same soil. Instead, they may plant corn one season, soybeans the next, then corn again.
Brenda Vander Mey is also with Clemson University. She says farmers should not endlessly work the same soil without putting back some organic matter.
James Frederick says farmers need information about what crops are best to plant. He says that sometimes disease-resistant crops will reduce harvests. He said a last choice would be chemical control. But he suggests using management methods first.
Another possible method of pest control is using genetically modified plants. They have had their genes changed to contain a special characteristic, like resistance to certain insects.
Brenda Vander Mey says she believes improvements in plants can be very helpful. She noted the example of genetic engineering that makes rice more nutritious by producing beta carotene.

A number of non-governmental and other organizations in many countries provide education in IPM. Farmers can get information meant for the needs of their own land. They can learn to recognize possible problems and how to plan crops to help prevent failures.
在很多国家,一些非政府和其他组织为农民提供病虫害综合防治课程。农民可以根据自己土地的需求获得相关信息。他们能学习辨别可能存在的问题,以及如何规划农作物种植以防止歉收。
Paul Jepson heads the Integrated Plant Protection Center at Oregon State University. He says farmers who have attended field schools in Asia and Africa have increased the use of IPM. And he says this has cut pesticide use.
保罗·杰普森(Paul Jepson)是俄勒冈州立大学综合植物保护中心(Integrated Plant Protection Center)
主任。他表示,亚洲和非洲参加过田间学校的农民使病虫害综合防治应用水平得到了提高,同时,这还降低了农药的使用。
James Frederick is an IPM expert with Clemson University's Pee Dee Research and
Educational Center in South Carolina. He says one basic IPM method is to plant as early in the season as possible so that most of the crop will be in by the time a disease or pest arrives. 詹姆斯·弗莱德瑞克(James Frederick)是南卡罗来纳州克莱姆森大学佩徳埃研究和教育中心的病虫害综合防治专家。他表示,病虫害综合防治最基本的一个方法,就是在当季时尽早播种,这样,当病虫害来临时大多数农作物已成熟收获。
Not all insects are pests. Some are helpful. IPM programs help farmers learn to identify different kinds.
并非所有昆虫都是害虫,有一些昆虫是益虫。病虫害综合防治项目帮助农民鉴别昆虫的不同种类。
Another IPM method is rotating crops. Farmers do not plant the same crop season after season in the same soil. Instead, they may plant corn one season, soybeans the next, then corn again.
另一个病虫害综合防治的方法是作物轮作。同一块地不要每季都种同种农作物,而是这季种玉米,下季种大豆,再下季再种玉米。
Brenda Vander Mey is also with Clemson University. She says farmers should not endlessly work the same soil without putting back some organic matter.
布兰达·凡梅伊(Brenda Vander Mey)也在克莱姆森大学工作。她表示,农民不能无休止耕种却不将有机物复耕还田。
James Frederick says farmers need information about what crops are best to plant. He says that sometimes disease-resistant crops will reduce harvests. He said a last choice would be chemical control. But he suggests using management methods first.
弗莱德瑞克表示,农民需要了解哪些作物最适合种植。有时,抗病性农作物会减少收成。病虫害防治最后的办法才是化学控制,首先应该使用综合防治办法。
Another possible method of pest control is using genetically modified plants. They have had their genes changed to contain a special characteristic, like resistance to certain insects. 另一个控制虫害的办法就是采用转基因作物。转基因作物的基因进行了重组,以携带某些特殊性状,例如抵抗某些特定昆虫。
Brenda Vander Mey says she believes improvements in plants can be very helpful. She noted the example of genetic engineering that makes rice more nutritious by producing beta carotene.
凡梅伊表示,她相信农作物基因改良会有很大帮助。她列举了一个通过制造β-胡萝卜素使大米更有营养的基因工程的例子。
