What Is Potato Plant Pesticide ?
| Potatoes are eaten all over the world and are popular tubers even with young children who would do anything to get mashed potatoes or French fries or chips. However, potato plant in the US is susceptible to pests and diseases, and that is why potato plant pesticide is used quite frequently to ensure the best yield.
Potatoes in fall are grown across northern United States, right from Maine to Washington. In nearly 11 states, potato plant pesticides are used; and this works out to 81 percent of the fall potato acreage. However, in states like Minnesota and North Dakota, where rainfall is low, just 40 to 50 percent of the acreage is treated with potato plant pesticides.
Nearly all states in eastern part of America have problem with fungus because of the relatively high humidity. This means that the potato plant is easily infected with fungi resulting in high use of pesticides for fungi. In contrast, arid and dry areas of western US do not have this problem so potatoes grown there are not treated with pesticides to combat fungus.
The most common pests that attack potato plants are Colorado potato beetles, aphids and leafhoppers, It has been seen that the Colorado potato beetle has developed resistance to potato plant pesticide which include organophosphorus insecticides and synthetic pyrethroids. The most commonly used potato plant pesticides throughout America are esfenvalerate, methamidophos and phorate. Even carbofuran and phospamidon are used against Colorado potato beetle. However, the EPA (Environmental Protection Agency) wants to ban granular formulations of carbofuran because they are associated with bird mortality.
