Pertanyaan

With the increasing concern about use and misuse of pesticides in commercial agriculture and home gardens, more and more inquiries for “organically grown” commodities are received every year. Non-chemical control practices for plant diseases have been known and recommended for years. The backbone of any integrated pest control program must always include cultural and sanitation practices, two important components of non-chemical disease control. Unfortunately, disease problems may begin as soon as seeds are planted and can continue into harvest and storage. Plant diseases may be caused by several different living pathogenic organisms such as fungi, bacteria, viruses. Phytoplasmas, and nematodes. In addition to these parasitic organisms, non-living factors such as deficiencies or excesses of water, light, temperatures, air pollution, pesticides, and nutrients can either presdispose a plant to disease or directly cause plant injury. Fortunately, many disease problems can be prevented or controlled without the use of pesticides. Effective plant disease control must begin at the onset of disease or even before symptoms appear. Several non-chemical practices that can reduce plant loss are as follows. First is resistance. Effective plant disease control through resistance (or a plant’s tolerance or immunity to a disease) is based on the knowledge of diseases known to occur in an area. Selection of resistant plants may eliminate many disease problems. Exclusion, another non-chemical practice, is preventing the entrance and establishment of disease causing organism (pathogens) into arcas where plants are grown. This means avoid bringing diseases into and/or moving them around in the garden. Use certified, disease-free seeds or transplants in sterilized beds or buy them from a reputable dealer. Also, avoid transporting soil or tools from knowm disease areas to disease-free areas. Last but not least is eradication. Eradication is the elimination of the disease-causing organism after it has become established on a plant. Eradication can be accomplished by sanitation, crop rotation, fallowing, and soil sanitation treatments. It can be predicted based on the passage that ....

  1. the use of pesticides in commercial agriculture will increase 

  2. non-pesticides control for plant diseases will be a new trend in agricultural practices

  3. plants which have high resistance will be applicable in all areas

  4. using certified transplants will reduce the use of pesticides 

  5. eradication practices should be conducted before the symptoms appear

Pembahasan

Paragraf satu pada teks di atas menjelaskan tentang meningkatnya kekhawatiran mengenai penggunaan pestisida, dan praktek kontrol non-kimia yang telah direkomendasikan selama bertahun-tahun. Dapat diprediksikan kemungkinan terciptanya tren baru dalam pertanian yaitu kontrol tanaman non-pestisida. Hal tersebut dapat diprediksikan dari informasi pada paragraf pertama dan juga dari paragraf-paragraf selanjutnya yang menjelaskan berbagai cara dan penanggulangan masalah tanaman tanpa penggunaan pestisida sehingga pilihan jawaban yang tepat adalah (B).
