This study aims to evaluate the interest of using an under-vine cover crop as a sustainable management tool replacing herbicides or tillage to control weeds, evaluating its effects on yield and berry parameters in a semi-arid climate. The performance of Trifolium fragiferum as an under-vine cover crop was evaluated in 2018 and 2019 in a Merlot vineyard in Traibuenas (Navarra, Spain). This trial showed that the soil under the vines was covered by 80 % of the cover crop in August 2018 and 100 % in Aug 2019, with clover (T. fragiferum) comprising around 26 % and 70 % of the cover crop surface, respectively. The presence of the cover crop only reduced the number of shoots in the second year, although both years there was an increment in water stress. Neither yield, cluster weight nor berry weight were affected by the presence of the under-vine cover crop. Similarly, no changes in grape composition were observed. The use of T. fragiferum-like cover crops under the vine allows for better control of weeds, provided a good installation is achieved. In the first two years, this cover crop reduced vegetative growth and increased water deficit slightly. However, no changes in yield and grape composition were observed.In a context of herbicide suppression and search for sustainable management, under-vine clover cover crops constitute a viable alternative in semi-arid regions provided drip irrigation can be applied.

SUMMARYThe potential of winged bean as a multipurpose legume cover crop was shown in field trials by its abundant vegetative growth throughout the growing period of two years. Protein contents of the dry matter of the whole plant, vegetable pods, seeds and tubers were in the range 22–34, 25–30, 32–38 and 16–19%, respectively. In a comparison of two cultivation methods, significantly higher yields were obtained from staked plants than from those grown without supports; protein contents, however, remained constant.

Carbofuran, oxamyl, aldicarb and fenamiphos treatments were tested for control of grape phylloxera [Daktulosphaira vitifolii (Fitch)] on ungrafted Cabernet Sauvignon grapevines in central Victoria. All insecticides were applied as granular formulations to the root zone of grapevines. Oxamyl was also tested as a foliar spray. Carbofuran was the most effective treatment, although aldicarb and oxamyl reduced phylloxera populations at some sampling periods. Fenamiphos did not control phylloxera. Vegetative growth, yield and root mass of infested grapevines declined during the 3 years of the experiment. In the third year, carbofuran- treated vines had significantly (P=0.05) greater fruit yield and more vegetative growth than control vines, but were performing poorly in relation to yields expected from uninfested vines. It is concluded that carbofuran treatment combined with optimum viticultural management may delay or reduce the decline of phylloxera infested grapevines. However, replanting with vines grafted to resistant rootstocks is a preferable long-term solution.

AbstractYellow disease is a complex disease caused byFusarium sp., Phytophthora sp., and nematodes. Infectedplants were quickly killed and were difficult for replanting,causing significant losses for the growers. Various controlmethods were examined including the use of bioconrolagents and cover crop Arachis pintoi. The researchobjective was to determine the ability of biocontrol agentsand A. pintoi to improve pepper growth and reduce yellowdisease incidence on pepper plants in the field. Researchresults showed that the treatment of biocontrol andA. pintoi promoted vegetative growth of pepper plants, andincreased pepper height for up to more five times, andreduced yellow disease incidence to 30%AbstrakPenyakit kuning merupakan penyakit kompleks yangdisebabkan oleh Fusarium sp., Phytophthora sp. dannematoda parasit.

Prohexadione Calcium

Prohexadione-calcium (prohexadione-Ca) was evaluated for its ability to suppress vegetative growth of grapevines (Vitis vinifera L.) under field conditions. Two or three applications of 250 mg·L-1 prohexadione-Ca reduced primary shoot growth of `Cabernet Sauvignon', but had little effect on other canopy characteristics or cane pruning weights. The reduction of shoot growth was not persistent and shoot hedging was ultimately needed to avoid canopy shading. Similarly, three applications of either 125, 250, or 375 mg·L-1 prohexadione-Ca reduced `Cabernet franc' shoot growth, but again did not eliminate the need for shoot hedging. Cane pruning weights of `Cabernet franc' were unaffected by treatment, and canopy characteristics were generally not improved. Two prebloom and one postbloom application of 250 mg·L-1 prohexadione-Ca were evaluated on `Cabernet franc' and `Chardonnay' in separate field experiments. The prebloom treatments retarded shoot growth of `Chardonnay', but had no effects on `Cabernet franc' shoot characteristics. To retard shoot growth, prohexadione-Ca had to be applied prior to bloom; however, prebloom applications had the potential for severe reductions in crop yield.
