1. Effects of carbosulfan on pineapple (Ananas comosus (L.) Merr.) growth.
The effect of the systemic insecticide carbosulfan on the growth of pineapple, transplanted from in vitro cultures, was observed in a greenhouse experiment. Three doses of carbosulfan (10,25 and 50 ppm) were applied along with a control (no insecticide). the plants were harvested at 30, 60, 90, 120 and 150 days after being transplanted. The everage leaf leng

2. Thiamethoxan on sugar cane, common bean, soybean, citrus and coffee plants: parameters of development and biochemical aspects / Tiametoxam em plantas de cana-de-açúcar, feijoeiro, soja, laranjeira e cafeeiro: parâmetros de desenvolvimento e aspectos bioquímicos
Insecticides and fungicides are often studied to their efficiency in controlling pests and diseases, however can cause physiological effects little known that can affect crop growth. Thiamethoxan is a systemic insecticide from the neonicotinoid group, nitroguanidine family, which acts on nicotinic acetylcholine receptor of insects, damaging their nervous sys

3. Translocation of the insecticide thiamethoxam in the phloem of castor bean and coffee plants. / TranslocaÃÃo do inseticida tiametoxam no floema de mamoneira e cafeeiro.
It was aimed in this work to investigate the translocation of thiamethoxam in the phloem of castor bean plant, used as model plant, the influence of adjuvants on the penetration of this insecticide in the leaves of this plant and its translocation in the phloem of coffee plant. Castor bean plants with three weeks of age, growing in nutrient solution and coff

4. Genetically engineered broad-spectrum disease resistance in tomato
Resistance in tomato to the bacterial pathogen Pseudomonas syringae pathovar tomato requires Pto and Prf. Mutations that eliminate Prf show a loss of both Pto resistance and sensitivity to the organophosphate insecticide fenthion, suggesting that Prf controls both phenotypes. Herein, we report that the overexpression of Prf leads to enhanced resistance to a

5. Toxicological Properties of the Organophosphorus Insecticide Dimethoate
The results are presented of extensive toxicological studies on the systemic organophosphate insecticide dimethoate, and compared with published results from other laboratories. It behaves as a typical indirect anticholinesterase, by conversion in the liver to at least four short-lived active metabolites, whose hydrolysis products are rapidly excreted, mainl

6. Herbivores cause a rapid increase in hereditary symbiosis and alter plant community composition
Microbial symbioses are ubiquitous in nature. Hereditary symbionts warrant particular attention because of their direct effects on the evolutionary potential of their hosts. In plants, hereditary fungal endophytes can increase the competitive ability, drought tolerance, and herbivore resistance of their host, although it is unclear whether or how these ecolo

7. Fungal toxins bind to the URF13 protein in maize mitochondria and Escherichia coli.
Expression of the maize mitochondrial T-urf13 gene results in a sensitivity to a family of fungal pathotoxins and to methomyl, a structurally unrelated systemic insecticide. Similar effects of pathotoxins and methomyl are observed when T-urf13 is cloned and expressed in Escherichia coli. An interaction between these compounds and the membrane-bound URF13 pro
