About one hundred eggs are laid in batches, 2 to 5 cm (0.8 to 2.0 in) beneath the soil and hatch after about two weeks. The larvae develop in the soil for two to four years. They feed on seeds and seedlings and the new tillers of cereal crops, and gnaw their way into roots, finding their food by smell.
Copper ions release more readily under acidic conditions and copper pesticides, except copper sulfate pentahydrate, should not be used with acid forming products. [10] Copper fungicides can be highly effective if applied prophylactically and with complete coverage of all plant foliar surfaces, including the undersides of leaves where the ...
An obvious side effect of using a chemical meant to kill is that one is likely to kill more than just the desired organism. Contact with a sprayed plant or "weed" can have an effect upon local wildlife, most notably insects. A cause for concern is how pests, the reason for pesticide use, are building up a resistance.
Fungicide residues have been found on food for human consumption, mostly from post-harvest treatments. [16] Some fungicides are dangerous to human health, such as vinclozolin, which has now been removed from use. [17] Ziram is also a fungicide that is toxic to humans with long-term exposure, and fatal if ingested. [18]

Food handling establishments (places where food products are held, processed, prepared or served) are included in the food tolerance of 0.1 ppm for chlorpyrifos. Food handling establishments may use a 0.5% solution of chlorpyrifos solely for spot and/or crack and crevice treatments. [137] Food items are to be removed or protected during treatment.
[5] [6] In a non-food crop such as cotton, reliance on natural frost may be too late to be effective in some regions. Thus leaves that remain on the cotton plant will interfere with mechanical harvesters and stain the white cotton resulting in a lower quality grade; herbicides which cause both defoliation and desiccation reduce these problems.

Pesticides, because they are toxic chemicals meant to kill pest species, can affect non-target species, such as plants, animals and humans. Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, because they are sprayed or spread across entire agricultural fields. [ 1 ]
