In past work, dichloropropene + 17% Pic (1,3-D + Pic) at 327 L·ha–1 plus pebulate provided good control of nematode, soil fungi, and nutsedge in mulched tomato (Lycopersicon esculentum Mill.) and is considered the best alternative for methyl bromide (MBr) + chloropicrin (Pic), which is scheduled for phase-out in the United States by Jan. 2001. Metam-sodium did not provide acceptable pest control. In the present study, metam-Na (295 L·ha–1 combined with Pic (168 kg·ha–1) + 4.5 kg·ha–1 pebulate, and 1,3-D + 35% Pic at 168 and 225 L·ha–1 + pebulate were compared to MBr-Pic (98-2% at 345 kg·ha–1 and 67-33% at 505 kg·ha–1). Fumigants were injected into the bed except metam-Na and pebulate were surface-applied and incorporated and drip tubing and mulch were applied. Marketable yields with MBr-Pic, 225 L·ha–1 1,3-D + Pic, and metam-Na + Pic were higher than with the check. Yields with metam-Na alone or with additional water before transplanting were similar to the check. Nutsedge was controlled with MBr-Pic and all treatments with pebulate. Nematode root-gall ratings were high on tomato grown without fumigants (8.9 rating on a scale of 0 to 10 with 0 = no galling), low with MBr-Pic (0.33), and intermediate with all other treatments (2.2 to 5.5) except with 168 L·ha–1 1-3-D + Pic (8.3). This study indicates that metam-Na + Pic + pebulate also is a possible alternative to MBr-Pic for tomato.

Tomato (Lycopersicon esculentum Mill.) was grown to evaluate various chemicals as possible alternatives to methyl bromide soil fumigation. Due to a combination of weeds, nematodes, and soil fungi, the use of a broad-spectrum fumigant has been essential for economical tomato production in Florida. Methyl bromide (MBr) and combinations of MBr with chloropicrin (Pic) are the fumigants of choice for most growers using polyethylene mulch culture. In 1991, MBr was allegedly associated with stratospheric ozone depletion. The U.S. Environmental Protection Agency has since mandated a phaseout of MBr for soil fumigation in the United States by the year 2001. At three locations in Florida, alternative soil fumigants were evaluated, including soil injected 98% MBr—2% Pic at 450 kg·ha-1, 67% MBr—33% Pic (390 kg·ha-1), Pic (390 kg·ha-1), dichloropropene + 17% Pic (1,3-D + Pic) at 327 L·ha-1, and metam-sodium (935 L·ha-1). Also, metam-sodium and tetrathiocarbonate (1870 L·ha-1) were applied by drip irrigation. Dazomet (450 kg·ha-1) was surface applied and soil incorporated. Pebulate (4.5 kg·ha-1) was soil incorporated with some treatments. Pic and 1,3-D + Pic treatments provided good to moderate control of nematodes and soil fungi except in one of the six studies, in which nematode control with 1,3-D was moderate to poor. Nutsedge densities were suppressed by addition of pebulate. Tomato fruit yields with 1,3-D + Pic + pebulate and with Pic + pebulate at the three sites ranged from 85% to 114%, 60% to 95%, and l01% to 119%, respectively, of that obtained with MBr treatments. Pest control and crop yield were lower with treatments other than the above pebulate-containing or MBr-containing treatments. These studies indicate that no one alternative pesticide can provide the consistent broad-spectrum control provided by MBr. Chemical names used: trichloronitromethane (chloropicrin); 1,3-dichloropropene (1,3-D); sodium N-methyldithiocarbamate (metam-sodium); sodium tetrathiocarbonate (tetrathiocarbonate); 3,5-dimethyl-(2H)-tetrahydro-l,3,5-thiadiazine-2-thione (dazomet); S-propyl butyl(ethyl)thiocarbamate (pebulate).

Methyl bromide (MeBr) is an important and effective soil fumigant commonly used to control weeds and soilborne pests. Because MeBr has been implicated as a contributor to the depletion of stratospheric ozone, it is scheduled for phaseout by 2005. This study examined nonchemical and chemical practices as alternatives to MeBr. Off-season flooding followed by a series of soil preplant chemical treatments [MeBr with 33% Pic; 1,3-D mixed with 17% (C-17) and 35% (C-35) Pic combined with Peb; and metam-Na combined with 1,3-D and Peb were evaluated on spring tomato (Lycopersicon esculentum Mill.) and eggplant (Solanum melongena) production in northern Florida. Pest control and tomato and eggplant yields were not significantly different between the flooded and non-flooded control plots. The most effective alternatives to MeBr were 1,3-D and Pic mixtures (C-17 and C-35) combined with Peb. Tomato and eggplant yields for these chemicals were statistically equivalent to that of MeBr. Tomato, but not eggplant, yield and nematode control were poor with metam-Na combined with 1,3-D and Peb in comparison to the other fumigant combinations. Chemical names used: 1,3-dichloropropene (1,3-D); trichloronitromethane [chloropicrin (Pic)]; S-propyl butyl(ethyl)thiocarbamate [pebulate (Peb)]; sodium N-methyldithiocarbamate (metam-sodium (metam-Na)].

Significance Trump announced on September 5 that his administration would phase out over the next six months the DACA programme, which protects undocumented migrants brought to the United States as children (known colloquially as ‘Dreamers’) from deportation and allows them to apply for renewable residency permits. While praised by immigration hardliners within the Republican caucus, many of the president’s party criticised the decision to add to the packed legislative calendar through the end of the year and heighten uncertainty for the estimated 790,000 DACA enrolees. Impacts Opposition from the agricultural lobby and large corporations will stifle Senator Tom Cotton’s plan to halve legal immigration. Trump’s deal with the Democrats on spending and borrowing through December will increase the minority’s leverage in DACA talks. Tackling DACA’s replacement and averting a December shutdown will sap congressional efforts to pass tax reform. Lawsuits from pro-DACA states and municipalities may slow DACA’s termination, but are unlikely to preserve it outright.

Minor Crops

The economics of pesticide production and registration has limited the number of pesticides registered for use in minor crops relative to agronomic crops. Current regulations such as the Food Quality Protection Act may further reduce the number of efficacious compounds registered for use on minor crops. Traditionally, the lack of registered pesticides for minor crops has been offset by soil fumigation. However, methyl bromide use is scheduled for phase-out in the United States by 2005, leaving a pest control vacuum in some crops. Loss of methyl bromide has stimulated research into the use of other soil fumigants for weed control. Methyl bromide, methyl iodide, propargyl bromide, 1,3-dichloropropene, and metham sodium have been tested alone and in combination with chloropicrin in laboratory experiments to determine their efficacy against Cyperus esculentus L (yellow nutsedge) tubers. All the fumigants controlled nutsedge equal to or better than methyl bromide and resulted in synergistic control when combined with chloropicrin. Although excellent weed control can be achieved with all the fumigants in the laboratory, weed control in the field with the same fumigant may result in poor or no control. Further research is necessary to optimize the field application of the remaining fumigants to maximize pest control. In the near future, to achieve the broad-spectrum pest control obtained with methyl bromide, growers will need to rely on multiple control strategies. The most promising replacement program for broad-spectrum pest control includes dichloropropene/chloropicrin fumigation followed by a herbicide program or mechanical weed control. To control problem weeds that are not controlled with the in-season herbicide program, a chemical fallow program should be instituted in the off-season to reduce weed pressure during the cropping season.

Traditional Fishing

In recent years, many nations have made claims of extended maritime jurisdiction or exclusive control for various purposes, and sometimes have claimed sovereignty over areas of sea far beyond the three-mile territorial sea traditionally claimed by many nations. A primary objective of many of these claims has been control over fishing in coastal waters, with the purpose of reserving for the exclusive use of fishermen of the coastal state the fish resources in the waters claimed, or of controlling the activities of foreign fishermen and possibly exacting fees for the privilege of continued fishing. The nature of most claims of authority to regulate the taking of fish in coastal waters is such as to exclude foreign fishermen, such claims having as their basic purpose unconditional right of exclusion. What rights exist for displaced fishermen exist as a matter of comity, i.e., friendship between friendly nations, and as such form no basis for claims of legal right to recompense (although the governments of fishermen who are expelled without a phase-out period may justifiably respond in like unfriendly manner, enacting restrictive tariffs or similar economic handicaps). Several countries have made provision in their own laws for recognition of “traditional” or “historic” fishing for foreign fishermen on a basis of reciprocity, i.e., their fishermen would have similar rights in the exclusive fisheries zone of the foreign nation whose fishermen were permitted to continue fishing. Most such laws have been very recent. The problem is not new, however. Problems of access to the North Atlantic fisheries embroiled the United States and Great Britain immediately after the Revolutionary War, and were not resolved until 1910 by action of the Permanent Court of Arbitration at The Hague. Pelagic sealing inflamed relations between the United States and other nations in the late 19th century, requiring arbitration for settlement.

We analyzed India’s export competitiveness in the textiles and clothing (T&C) sector in the United States. The T&C industry is traditionally important for the Indian economy due to its significant contribution to export, employment, and industrial production. However, the competition in the global T&C market intensified after the Multi-Fiber Arrangement phase-out in 2005. Therefore, it is necessary to examine the export competitiveness of India’s T&C sector in the U.S., India’s largest export destination and one of the world’s largest consumers of T&C. In this study, we calculated the comparative advantage of India’s T&C based on Revealed Comparative Advantage (RCA), Market Comparative Advantage (MCA), and Comparative Advantage by Countries (CAC). Our analysis shows that India had a comparative advantage in the T&C sector in the U.S. from 1991 to 2017, despite intensified competition in the global market.
