The word "pesticide" refers to any substance used to control something undesirable, including insects, slugs and snails, rodents, weeds, and disease. My Question: Which ones kill on contact, and have good residual effectiveness? Last summer I used a combination of natural and Ortho products every 7 - 10 days. Gardens Alive and other natural gardening catalogs feature a vast array of pesticide and fungicide products. but they don't seem to have an effective residual presence on plants like my roses. I have tried using products like Pyola, Neem Oil, etc. Mike: Applying systemic chemical pesticides is a nuisance, and the products can be so dangerous that ORTHO has taken its systemic pesticides off the market. The best way to minimize human toxicity and prevent environmental pollution by an increased rate of degradation is to rely on natural pesticides.Q. Those pesticide residues in water can enter the rivers and seas theirs by deteriorating the health of water and land animals. The pesticides entering water resources travel to other places spreading the pollution of this pesticide.ĭegradation of pesticides in soil occurs over weeks, so the pollution takes time to decrease. Those food grains grown in polluted pesticide soil enter the food chain of all the living animals. in homes regularly enter into the physiology of humans and animals on breathing. In homes and gardens, when used as mosquito repellents, bed bug spray, etc. These pesticides are spread into the air, water bodies like rivers, canals, soil due to their regular use in the form of spraying, powders, solutions in agriculture. The Environmental effects of pesticides are a concern now. These biopesticides are less toxic to humans and also very compatible with the crop and soil. They are made from biological material or are a living agent like bacteria or fungus is used. Many pesticides under red labels are banned now.īesides the above chemical pesticides and insecticides, there are many natural ones. The colors on pesticides like Red, Yellow, Green, or BlueĪre mentioned based on their order of decrease in poisonous effect to humans. However, based on their toxicity towards humans, they are graded.Īs indicated by their labels, pesticides are classified into four categories. Insecticides and pesticides are equally toxic. Types of insecticides and pesticides based on their toxicity Pesticides in the food make the quality of food grain less demanding in the market, and hence the farmer gets a low price for his yield. These industries suffer due to heavy pesticide pollution. ♦ Honey bees form nectar and are useful for honey manufacturing industries. ♦ Further, they kill useful insects like honey bees and butterflies, enhancing cross-pollination in crops for better yield. Once inside the body, they cause various nervous system-related disorders, nausea, vomiting, sedation, burr vision, and sometimes even death. ♦ Chemistry of pesticides is organophosphate in nature. Due to soil, air, and water pollution, these chemicals and pesticides get into the body. The effect is poisonous, and many physiological systems are affected by them. Pesticides toxicity has hazardous effects on plants, soil, humans, animals, and birds. They even prevent the spread of diseases like malaria, chikungunya, filaria, etc.
