Source: inpEV　

The Brazilian pesticide container disposal organization, the inpEV, reports that the collection volume of empty containers rose by 17% compared with the same period last year to 9,481 tons in the first three months of 2012. Mato Grosso, Sao Paulo and Parana recorded higher recycling volumes.
According to the inpEV, various activities are designed to educate the farmers about the importance of washing pesticide containers after use and returning them to the location indicated on the invoice. The latest campaign the "Pride of the Nation", which supported by The Ministry of Agriculture, Livestock and Supply (MAPA), will be broadcast on national television until May.

Efficiency of using dicamba-dimethylamine in the orchard against broad-leaved perennial weeds

dicamba - dimethylamine at 1-5 kg/ha was use towards development weeds round drawers in a bearing apple orchard on a chernozemic loam land in 1967-70 in June. The 2 kg/ha rate showed complete control of field bindweed Convolvulus arvensis, crawl thistle Cirsium arvense & maize sowthistle Sonchus arvensis in December 1967; 94% of perennial weeds & all yearly grasses were controlled. Dicamba at up towards 2 kg/ha did not affect the yield, calibre or safekeeping properties of apples. Application of 2 kg/ha every twelvemonth in June is suggested.

Pesticide use in Indonesia is alarming

Source:Jakarta Globe

Indonesian farmers use an alarming amount of pesticides — including some with illegal toxic chemicals — on their crops, the People’s Coalition for Food Sovereignty (KRKP) said.
The NGO cited a 2011 survey of 306 farmers in Central Java that found that farmers used pesticides an average of 5.7 times per growing season.
"That is a very high use for farms,” KRKP official Said Abdullah said in Jakarta on Thursday.
Pesticides are big business in Indonesia. The local market reaches about Rp 6 trillion ($654 million) a year, Said said. That market includes 350 brands of fungicides, 600 brands of herbicides and 800 brands of insecticides registered with the Indonesian authorities, according to Ministry of Agriculture’s Pesticide Commission numbers.
And these figures don"t even include products that enter the country illegally, Said said.
"Between 10 and 12 percent of pesticides circulating in Indonesia are illegal,” he said.
Many of these chemicals contain harmful substances like organochlorine and organophosphate, Said said.
The one chemical, organophosphate, is considered hazardous, even in low doses, and its use is highly-regulated, or banned outright, in 23 countries. Organochlorine was present in the pesticide DDT, a chemical that caused massive ecological damage in the United States before its use was banned in the 1960s.
He called on farmers to adopt more environmentally-conscious and sustainable farming methods.

About pencycuron: a simple bioassay method of new fungicide against ricesheath blight-broad beau leaf method

By:　Zhang Suhua; Li Shuzheng;Yang Shuqin　
The aim of this study was to establish one easy and rapid fungicidal screening method.A“broad beau leaf method” appropriated for fungicidal bioassay of rice sheath blight was proposed. The experiment showed that the method was simple to prepare the meterials and masterthe technique. Antibiotic activity and action way of Pencycuron and Validmycin assayed by thismethod were the same as those reported in the literatures. Similar results were obtained by usingeither broad beau leaf method or seedling method.

Effect of herbicide dicamba on rabbit vaginal mucus membrane

Effect of dicamba and its active ingredient, dicamba (3,6-dichloro-o-anisic acid) was investigated employing rabbit mucus membrane irritancy test. Inflammatory changes which did not exceed an average score of 2+ were observed in the animals 48 hr after a single intravaginal application of dicamba (0.1 ml/rabbit) and dicamba (100 mg/rabbit). Persistent histopathological changes were observed in 1 out of 6 banvel-treated rabbits 15 days post-application. The results suggest that banvel and dicamba are not primary irritants but should nevertheless be employed with caution

U.S. EPA clarifies pesticide labeling requirements

Source:EPA News Release　

The U.S. Environmental Protection Agency has published a notice in the Federal Register announcing the availability of Pesticide Registration Notice 2012-1, titled Material Safety Data Sheets as Pesticide Labeling. This notice updates and clarifies PR Notice 92-4, titled Material Safety Data Sheets as Pesticide Labeling and is available at http://www.epa.gov/PR_Notices/.
The notice provides guidance to registrants on the relationship between EPA-approved labels for pesticides registered under the Federal Insecticide, Fungicide, and Rodenticide Act and the Material Safety Data Sheets required by the Occupational Safety and Health Administration (OSHA). Material Safety Data Sheets are also referred to as Safety Data Sheets.
OSHA requires Safety Data Sheets under its Hazard Communication Standard (HCS)(29 CFR 1910.1200) and recently published a final rule (77 Federal Register 17574-17896, March 26, 2012) to align its HCS requirements with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). The GHS is designed to provide a common and coherent approach to defining and classifying hazards and communicating hazard information on labels and safety data sheets. The system was developed based on major existing systems for industrial chemicals, pesticides, consumer chemicals and chemicals in transport, but implementation of the GHS would require some changes in all existing systems in order to achieve harmonization.
PR notice 2012-1 explains how registrants can ensure their FIFRA labeling and Safety Data Sheets comply with EPA’s requirements.
EPA recommends registrants include in their Safety Data Sheets the hazard information required on FIFRA labeling and a brief explanation for differences between that information and the Safety Data Sheet hazard information. The PR Notice includes sample language that may be used.
