SELECTIVITY OF LINURON HERBICIDE FOR CARROT WHEN SPRAYED IN POST-EMERGENCE Planta Daninha
CORREIA,N.M.; CARVALHO,A.D.F..
ABSTRACT Among the herbicides registered for carrot crop in Brazil, linuron is the most used one, according to horticulturists. However, there are few reports in the literature on its selectivity for the carrot plants. Therefore, the aim of this work is to study the selectivity of linuron herbicide for growing carrots, influenced by genotype, product dosing, and plant development phase at the time of application. This work included four experiments, one in greenhouse, and three in the field, in area of commercial carrot production. In the greenhouse, the experimental design was completely randomized in factorial scheme 4 x 2 x 3, with four replications. Linuron, at doses 0, 225, 450 and 675 g a.i. ha-1 was sprayed in plants with 1 and 2-3 true leaves of...

Selectivity of the plant growth regulators trinexapac-ethyl and sulfometuron-methyl to cultivated species Scientia Agricola
Correia,Núbia Maria; Leite,Gilson José.
The aerial spraying of plant ripeners on sugar cane (Saccharum officinarum L.) crops causes often the contamination of neighboring areas, which subsidizes formal complaints from the neighbors. These contaminations are due to spraying taking place during inadequate environmental conditions or from technical mistakes during the application. One of the most important causes of this contamination is the susceptibility of the species being cultivated surrounding sugar cane. In order to evaluate the effects of sugar cane plant ripeners trinexapac-ethyl and sulfometuron-methyl on peanuts, cotton, potato, coffee, citrus, beans, sunflower, cassava, rubber, soybean, and grapes, eleven experiments - one for each species - were carried out from May 2009 to Jan. 2010....

Selectivity of Herbicides Bentazon and Nicosulfuron for Crotalaria juncea Intercropped with Maize Culture Planta Daninha
NOGUEIRA,C.H.P.; CORREIA,N.M..
ABSTRACT The objective was to study the selectivity of herbicides bentazon and nicosulfuron, alone and in a mixture, to Crotalaria juncea, when established in intercropping with maize, as well as weed control and maize development in this production system. Two experiments were conducted in the field, in late harvest and in harvest periods. The experimental design was a randomized block, with 14 treatments and four replicates. Eight treatments with herbicides bentazon (720 and 960 g a.i. ha-1), nicosulfuron (16 and 48 g a.i. ha-1) and bentazon plus nicosulfuron (720 + 16; 720 + 48; 960 + 16; 960 + 48 g a.i. ha-1) were studied, besides six controls (single crop maize and sunn hemp, with and without weed control, intercropped maize and sunn hemp, with and...

Selectivity of Herbicides to Native Tree Species in Brazil Planta Daninha
OLIVEIRA,L.; SILVA JR,A.C.; GONÇALVES,C.G.; PEREIRA,M.R.R.; MARTINS,D..
ABSTRACT: Weeds are one of the main obstacles in the recovery of degraded areas. This research aimed to study the selectivity of herbicides on Trema micrantha (Jamaican nettletree), Schinus molle (Peruvian peppertree), and Apuleia leiocarpa (garapeira) seedlings. An experiment was installed in Junqueirópolis and another in Jaboticabal/SP, Brazil. The experimental design used was completely randomized design with four replications. Treatments consisted of clethodim + fenoxaprop-p-ethyl (50 + 50 g a.i. ha-1), sethoxydim (184 g a.i. ha-1), quizalofop-p-ethyl (75 g a.i. ha-1), nicosulfuron (50 g a.i. ha-1), fluazifop-p-butyl (125 g a.i. ha-1), fomesafen (225 g a.i. ha-1), haloxyfop-methyl (48 g a.i. ha-1), bentazon (720 g a.i. ha-1), chlorimuron-ethyl (15 g...

Differential Tolerance of Clones of Eucalyptus grandis Exposed to Drift of the Herbicides Carfentrazone-Ethyl and Glyphosate Planta Daninha
SANTOS,S.A.; TUFFI-SANTOS,L.D.; ALFENAS,A.C.; FARIA,A.T.; SANT’ANNA-SANTOS,B.F..
ABSTRACT: Drift of the herbicides carfentrazone-ethyl and glyphosate may affect the initial growth of eucalyptus. This study aimed to assess the effect of carfentrazone-ethyl and glyphosate drift on photosynthesis, leaf morphoanatomy, and initial growth of two clones of Eucalyptus grandis. Two experiments were carried out in a 2 x 4 factorial scheme, in which factor 1 was represented by two clones of E. grandis and factor 2 by four herbicide underdoses (control, 86.4 g a.e. ha-1 of glyphosate, 3.0 g a.e. ha-1 of carfentrazone-ethyl, and the mixture of 86.4 g a.e. ha-1 of glyphosate + 3.0 g a.e. ha-1 of carfentrazone-ethyl). Herbicide application was carried out by simulating the drift in the lower third of seedling canopy. Assessments were performed 23...

Application of Post-Emergence ALS Inhibitor Herbicides Associated or Not to Glyphosate in RR/STS Soybean Planta Daninha
SILVA,A.F.M.; ALBRECHT,A.J.P.; ALBRECHT,L.P.; VICTORIA FILHO,R.; GIOVANELLI,B.F..
ABSTRACT The aim of this study was to evaluate the selectivity of ALS inhibitor herbicides, applied isolated and associated with glyphosate in post-emergence of soybean cultivar presenting the RR/STS technologies. The experimental design was a randomized block with four replications and ten treatments. The treatments consisted of the application of glyphosate and ALS inhibitors herbicides, isolated and associated with glyphosate. The application of treatments occurred in V4 stage of plant development. The evaluation of phytointoxication, SPAD index was conducted, as well as variables related to agronomic performance (height, number of pods per plant, yield and mass of a thousand seeds). Yet additional test with the same cultivar and treatment was conducted...
