“…There are reports associating the cracking of tubers to the presence of ALS-inhibiting herbicides (acetolactate synthase) such as nicosulfuron, metsulfuron and tribenuron, EPSPs-inhibiting herbicide (5-enolpyruvylshikimate-3-phosphate synthase) such as glyphosate and auxin mimics such as dicamba and clorpyralid (Eberlein et al, 1994;Wall, 1994;Novo & Miranda Filho, 2006;Hutchinson et al, 2014). No reports were found linking HPPD inhibitor herbicides to any physiological disorder in potato tubers.…”

ABSTRACT. Crop rotation improves potato (Solanum tuberosum L.) crops; however, in some cases, it can have some negative effects due to the herbicides previously used in crops under rotation. These effects are the decline in the yield and the appearance of physiological disorders, including cracked tubers, which impair the quality and economic value of the potato. Two field experiments were performed with applications of tembotrione and atrazine, alone or in combination. In the Rio Paranaiba (Minas Gerais State) area, in clay soil, the herbicides were applied at post-emergence in corn (Zea mays L.). After corn harvest and soil preparation, the potatoes were planted. In the Serra do Salitre (Minas Gerais State) area, in the medium texture soil, the herbicides were applied and incorporated into the soil, and the potatoes were planted the day after. No injuries were found in the shoots. Decline in the potato yield was found only in the medium texture soil (Serra do Salitre). Atrazine did not affect the quality of potato tubers. In the two areas, tembotrione promoted cracks in "Atlantic" potato tubers.Keywords: Atlantic; herbicide; physiological disorder; Solanum tuberosum.Carryover de tembotrione e atrazine afeta a produtividade e a qualidade de tubérculos de batata RESUMO. A cultura da batata (Solanum tuberosum L.) é favorecida pela rotação de culturas e, em alguns casos, desfavorecida pelos efeitos adversos dos herbicidas utilizados anteriormente nas culturas em rotação. Esses efeitos são redução de produtividade e desordens fisiológicas como, por exemplo, rachaduras de tubérculos, que reduzem a qualidade e valor comercial da batata para consumo in natura ou processamento industrial. Em dois experimentos de campo foram realizadas aplicações de tembotrione e atrazine, isolados ou em mistura. Na área de Rio Paranaíba (Estado de Minas Gerais) em solo de textura argilosa, os herbicidas foram aplicados na cultura do milho (Zea mays L.) em pós-emergência e na área de Serra do Salitre (Estado de Minas Gerais) em solo de textura média, foram aplicados e incorporados um dia antes do plantio da batata. Não foram observadas injúrias na parte aérea das plantas. A produtividade de batata foi reduzida somente no solo de textura média (Serra do Salitre). O atrazine não influenciou a qualidade dos tubérculos de batata. Nas duas áreas o tembotrione causou rachaduras em tubérculos de batata "Atlantic".

“…Plants that received 215 g ha -1 glyphosate during H in 2007 had the lowest total yield, almost 5.5 times less than the nontreated and almost half the total yield, when compared to plants receiving the same glyphosate dose but at the TI stage. Similarly, Hutchinson et al [30] reported that a sublethal glyphosate dose to potato at the H stage reduced yields more than 40% compared to the nontreated yields. However, in their study, they also subjected plants to sublethal glyphosate doses when the plants were only 10-15 cm tall and concluded that these plants would most likely recover even from relatively high glyphosate doses.…”

“…Hutchinson et al [30] reported that visible injury tends to be greater when potatoes contact glyphosate during vegetative growth, while visible injury from glyphosate is less apparent when tubers are bulking and are the primary sink. When the daughter tubers, or next field generation of tubers, were planted back the next season, tubers that received glyphosate during bulking had a reduced emergence rate, stem number, and marketable yield.…”

The herbicide glyphosate is used in many countries because of low cost and effective weed control, but low levels of glyphosate on potato can reduce yield, marketability, and seed quality. Glyphosate is a phloem-mobile herbicide that can translocate to tubers, causing malformations that reduce the quality of current-season production. Potato plants are most susceptible to glyphosate at the hooking or tuber initiation stage. Tubers exposed at these stages often will become malformed and yield loss can occur. Seed production can be affected because glyphosate degradation is slow and it translocates to tubers. Seed potato exposed to glyphosate can store glyphosate residues until they are planted the next season. Tubers planted with glyphosate residues will have an erratic and slow emergence pattern, bending and twisting of leaves, multiple shoots from eyes, "candelabra" or "cauliflower" formation of shoots, or completely inhibited shoot growth, depending on the rate and cultivar. Glyphosate-affected seed tubers produce less tuber set and tubers with reduced weight. Tubers suspected to have glyphosate injury should be tested at a reputable laboratory to confirm glyphosate residues are present. Good management practices can help prevent potato from being exposed to glyphosate.

“…Chemicals like; ethylene (Prange et al , 1997(Prange et al , 1998Daniels-Lake et al 2005), ozone ( Daniels-Lake et al 1996), glyphosate Ezekiel 2006a, 2006b), hydrogen peroxide (Afek et al 2000;Kleinkopf et al 2003;Bajji et al 2007), 1, 4-dimethyl naphthalene 1, 4-DMN (de Weerd et al 2010;Campbell et al 2010;Canada 2011;Potato 2012), 2, 6-diisopropyl naphthalene (2, 6-DIPN) (Lewis et al 1997) were also tested to control the sprout growth on potatoes. Ethyl ester of 2, 4-dichlorophenoxy acetic acid (2, 4-D), ethyl ester of 2, 4, 5-trichlorophenoxy acetic acid (2, 4, 5-T), imazethapyr and glyphosate are herbicides like CIPC and they are also reported to be effective and better than lower alcohols and acetaldehyde in suppressing the sprout growth on potatoes (Burton 1989;Burton et al 1992;Tayler et al 1996;Paul and Ezekiel 2002;Paul and Ezekiel 2006a, b;Paul et al 2014;Hutchinson et al 2014). Perhaps in view of either practical problems or due to issues related to human health and environment safety further work with these herbicides as an alternative to CIPC was not taken up.…”

Sprout suppression on potato: need to look beyond CIPC for more effective and safer alternatives

World over, potatoes are being stored at [8][9][10][11][12]. This is the most common way of long-term (up to 6 to 9 months) storage of potatoes. The benefit of storing the potatoes within the temperature range of 8-12°C is minimum accumulation of sugars in stored potato tubers. In sub-temperate, sub-tropical and tropical countries of the world, short-term (3 to 4 months) storage of potatoes is being done by non-refrigerated traditional/on-farm methods. These short-and long-term storage methods keep the stored potatoes suitable not only for table purpose but also for processing. However, once the natural dormancy period of potato is over, the prevailing temperatures in these storage methods favour sprouting and sprout growth. Therefore, use of some sprout suppressant to check the sprout growth becomes essential under these methods of potato storage. CIPC [Isopropyl N-(3-chlorophenyl) carbamate] is the most wide spread and commonly used sprout suppressant on potatoes. CIPC has been in use for more than 50 years and research carried out over such a long period use of CIPC has not only enhanced our understanding of its properties and chemistry but also about the production and toxicological status of its metabolites/ degradation products. Today, various safety issues and concerns have surfaced primarily due to continuous and longterm use of CIPC. This review presents an appraisal on CIPC and explains the reasons for the long-time dependence on this chemical as a potato sprout suppressant. Issues like maximum residue limit and acceptable daily intake limit are being discussed for CIPC. This article brings an update on practical aspects of potato storage, residue levels of CIPC, efficacy of CIPC as sprout suppressant and health and environmental safety issues linked with CIPC and its metabolites. The aim of this article is to find possible solutions, way outs and future plans that can make the sprout suppression of potatoes safer and more risk free.
